CCL-B Series

CDR Pompe CCL-B Series Centrifugal Pumps

The CCL-B Series uses a standard motor and close-couple execution to function properly. One distinction is the Plastic Lined Horizontal Single Stage Centrifugal Pump, which can complete both closed- and long-coupled processes.

Extra Features

The CCL/CCL-B Series provides many unique benefits to users. Take a look at the parts that make up the whole, and you’ll understand why CDR Pompe centrifugal pumps are excellent for heavy duty operations.

Lined Shaft Sleeve

CCL Lined Shaft Sleeve

The lined shaft sleeve uses a mechanical CSE seal design to prevent the metallic parts of the sleeve from coming into contact with any fluids in the pump. While it generally uses the standard PP lining in these models, it also accommodates other materials, like Hastelloy C.

In many instances, the impeller and the shaft sleeve the same. In these models, they’re separate. They were designed this way so damage to either part can be more easily replaced or repaired.

Another benefit of this separation is that you can feel more secure about the connection and seal created between the two. You have to push the lined shaft sleeve into position manually. As you do, the sleeve will push the O-ring against your impeller, providing a tight seal that lasts even if the pump itself fails. And, once fitted, the sleeve will synchronize with the shaft and the impeller, keeping all parts together even when the pump rotates in the opposite direction.

Lined Casing

CCL Lined Casing

The pump’s casing is made of ductile iron. In addition to making the pump vacuum-resistant, it also absorbs straining, external shocks and vibrations to prevent damage to the device itself. It is self-venting.

The lined casing also offers an optional draining casing add-on.

Seal Chamber

CCL Seal Chamber

The seal chamber keeps solid particles and slurry from contacting the seal, which can affect the pump’s efficiency. This chamber is wide and conical to ensure the entire seal is protected. It can handle all venting, flushing and draining operations.

Mechanical Seal Arrangements

Ensuring you have the proper seal for whatever fluids you’re pumping is essential to prevent dangerous leaks and optimize productivity. For example, clean fluid requires a TSI single internal seal, while corrosive fluids prefer a TSE single external seal. Dirty and aggressive fluids need a CSE single internal seal. For the most dangerous fluids, you will need a double tandem seal for the best chance against leakage.

Be sure to talk to our team regarding our wide selection of mechanical seals, including the:

  • TSI/TSI Double Tandem Mechanical Seal: For PLAN 53A/54. Ideal in situations where the media is dirty, unstable and unable to be released into the air.
  • TSI Single Internal Mechanical Seal: For PLAN 02. Excellent for clean or moderately contaminated media.
  • TSI Single External Mechanical Seal: For PLAN 02. Good for corrosive media without particles.
  • CSE Single Internal Seal Tapered Seal Chamber: Provides significant flexibility for sealing in corrosive, hazardous materials.
  • CSE-Q Single Internal Mechanical Seal With Quench: For PLAN 62, when necessary (after liquid crystallization). Provides options for working with corrosive, abrasive, dirty liquids. It has one of the simplest maintenance needs due to a semi-cartridge construction.

Shaft

Made with 400 series stainless steel, this shaft offers no leakage points and less than .05 mm shaft deflation. A long screw provides balance and rigidity as it connects the shaft to the impeller. Both the materials and its construction ensure the shaft will have a long, reliable life free of corrosion while improving the seal’s life.

Lined Impeller

CCL UCL Lined Impeller

The key-driven system for their Transfer Molding impeller eliminates the common start-up reverse rotation error and lets your pump get right to work. The sold metal configuration provides high chemical resistance, and the back vanes are ideal for the life span of the impeller, seal and bearing.

3-D View

Take a look at this three-dimensional view of the CCL/CCL-B Series. It provides an idea of how all the parts work together and whether its functions will be best for your industry’s needs. Pay special attention to the:

  • Shaft: It has been designed in the “dry shaft execution,” meaning the shaft and the medium never come in contact with one another.
  • Shaft sleeve: It’s made to be easy to replace, resulting in faster repair times and lower maintenance costs in the long run.
  • Bearing frame: You can use your preference of standard oil seals or labyrinth seal.
  • Oil sump: The sump has a bigger volume that most, ensuring the oil stays clean and cool.
  • Pump: The modular design allows for easy switching between close-coupled and long-coupled operations.
  • Casing and impeller: They’re designed using the transfer molding process and lined with PP casing.
  • CCL pumps: You can equip them to fit your needs, whether that’s with an open or closed radial impeller.
  • Wetted parts: The PP lining provides high levels of chemical resistance and a strong wall thickness for lined parts.

Typical Applications

These versatile pumps have a use in all kinds of industries. It’s suitable for handling hazardous materials that could be aggressive or corrosive, such as what you may find in fertilizer processing and other farming operations, fuel mining, treatment of water and air and RAEE or the recovery of precious metals.

CDR Pompe pumps are equipped with durable, reliable parts designed to work with even extensive heavy-duty service. They’ve been specially manufactured to fit with the chemical industry’s growing standards, similar to the hydraulic manufacturing of the UCL Series.

UCL Series

CDR Pompe UCL Series Centrifugal Pump

Like the CCL Series, the UCL Series boasts a back pull-out configuration, flexible coupling and durable bearing housing. It can execute close- and long-coupled operations and has a UCL-lined PFA.

UCL-B Series

CDR Pompe UCL-B Series Centrifugal Pump

The UCL-B Series pumps execute close-coupled operations using standard motors.

Extra Features

While much of the basics of the UCL/UCL-B Series match the manufacturing of the CCL/CCL-B Series, each part has a few distinct differences. Explore them closely so you can choose the pump model that most closely fits your industry’s pump needs.

Lined Casing

CCL Lined Casing

Strong, ductile iron encases peripheral fluoroplastic pump areas to protect it from vibration, pipe strain and external shocks during handling and movement. It also makes the casing vacuum resistant. The casing is self-venting and, if your uses require it, an optional draining casing can come with it.

Lined Impeller

CCL UCL Lined Impeller

Transfer Molding took this sold metal impeller and made it even more durable and chemical-resistant by adding Fluopolymers lining consisting of PP, PFA and PVDF – a collection of sturdy polymers that avoid chemical reactions while enhancing the impeller’s reliability mechanically. Using a system that’s key-driven, you no longer have to think about reverse rotations on startup. And thick back vanes aid the bearings and seal, providing all parts with a longer life span.

Lined Seal Chamber

ucl lined seal chamber

Choose a seal chamber lined with your preference of material – you can choose between PFA, PP or PVDF. All seals use a broad, conical build that’s equipped with breaking ribs. All chambers are made to push slurry and solids out of the seal’s way, as they can interrupt the media flow.

Mechanical Seal Arrangements

With the seal’s conical design, it can fit nearly any mechanical seal type, including both CSS single seals and CDC double cartridge seals. By providing a wide range of operations, you can procure maximum flexibility for any operation, even in challenging conditions. You can also adapt it to fir a number of UCL pumps.

Some of the common seal arrangements are:

  • Conventional Double Seal – Cylindrical Seal Chamber External Flushed – ISO 12756 –EX DIN 24960: Works similar to the CDC Double Cartridge Seal, with the necessary strength to prevent hazardous materials from leaking into the surrounding atmosphere and the ability to pump abrasive and dirty media.
  • Single External Seal Tapered Seal Chamber: Suits PLAN 02. This seal comes in a variety of materials by many brands, so you can use whichever you’re most comfortable with. The model version includes single PTFE bellow seals, which work best as external mountings.
  • CDC Double Cartridge Seal Tapered Seal Chamber: Good for PLAN 53A-54. This seal is one of the strongest available, designed for operations where leakage is immediately dangerous, such as with toxic or flammable materials. Because it doesn’t need the media to lubricate it, it’s also a good choice for working with unstable, dirty and polymerizing media.
  • Double Cartridge Seal Tapered Seal Chamber: Ideal for PLAN 52-53-54. It works similarly to the conventional double seal, but with the better maintenance of the cartridge configuration.
  • Faces Sealed in Diamond SiC: An immensely durable diamond coating provides a longer service life with practically no wear. It also contributes significantly to energy-saving costs.
  • CSS Single Internal Seal Tapered Seal Chamber: Works will for PLAN 62, as it’s also available in CSS-Q. A semi-cartridge configuration makes maintenance a breeze, even after working with corrosive and moderately dirty media. The metal and media parts never come in contact with one another so it’s also resistant to abrasive materials.

Shaft

This shaft is made from 400 series stainless steel, molded into a strong, rigid shaft that should provide less than .05 mm deflection of the shaft, providing a long, reliable seal life free of corrosion. The shaft is manufactured to ensure there are no weak points that could result in leakage of hazardous materials. It comes with a long screw that allows it to easily connect with the impeller.

Lined Shaft Sleeve

UCL Lined shaft sleeve

This part is separated from the impeller, allowing for an easier replacement when the need arises. It also constrains the damage to only the sleeve so the impeller does not need to be replaced along with it. In the case where failure occurs, the pump should still maintain a secure seal, as the sleeve pushes the O-ring into the impeller and cannot be adjusted without removing the sleeve.

The shaft sleeve is essential in creating a proper seal in the pump, and with the push-in-position design of this sleeve, you can feel confident in the manual security of the pump. Any part that could touch the media is coated with PFA and SiC to prevent corrosion, but you can easily change the material if you prefer a different lining, like Hastelloy C. Should the pump move in the wrong rotation direction on starting, the sleeve synchronizes with the impeller and shaft, preventing the seal from loosening.

3-D View

UCL diagram

This three-dimensional image gives you a bit more insight into how many facets of the UCL/UCL-B Series function. Note the:

  • Shaft: It employs the use of “dry shaft execution,” meaning it will not make contact with the media running through the pump.
  • Shaft sleeve: As a modular design element, you can easily remove, repair and replace it without damaging the surrounding parts. This makes the pumps easier to use and cheaper to maintain over time.
  • Bearing frame: Equip your frame with your choice of a standard oil seal or a non-contacting labyrinth seal.
  • Oil sump: The volume of the sump is increased compared to other models to ensure the oil is clean and cool when used.
  • Pump: Another modular design element that allows you to switch between close- and long-coupled operations.
  • Seals: You have your choice to customize your seals for whatever your job needs.
  • PFA/PVDF/PP components: These areas are manufactured using Transfer Molding processes.
  • Wetted parts: These parts start with a strong resistance to chemicals, which is further backed up with virgin PFA, PP or PVDF, depending on your preferences.

Technical Features

ucl bracket and bearing

Everything about the CDR Pompe UCL/UCL-B Series is created to be of the highest quality so it functions well in many applications for years to come. Explore some of the more technical features below to better understand why these pumps are modeled as they are.

Bearing Bracket for Long Coupled Execution

The bearing frame does more than just hold the bearings in place. Underneath it is an extra-large sump to hold an excess amount of oil, allowing for smoother bearing operations. The sight glass ensures you’ll have good oil levels at all time, and the breather plug at the top makes it simple for you to lubricate the frame and refill the reservoir below. There’s also a big drain plug at the bottom so replacing the oil is as easy as refilling it.

You can use two different types of seal protection for this bearing bracket – the standard oil seal, or a non-contacting labyrinth seal. The latter option provides a constant level oiler and conditions monitoring if you so choose.

Bearings

These bearings are designed to withstand 17,500 hours. That’s equal to over 729 days or nearly two years of straight pumping. You’ll find one tow of bearings on the frontal or impeller side of the pump and one pair of contact bearings on the rear side, sometimes called the motor side. Both configurations boast high axial load ratings.

Paint Coatings

UCL paint coating quality

Any metal surfaces on the pump are costed with three paint layers. These layers are high-performing and prevent corrosion and damage for as long as possible. The layers are:

  1. Epoxy enamel paint or aliphatic acrylic polyurethane
  2. Epoxy amidic modified vinyl
  3. Epoxy zinc paint

Upon request, we can also discuss using EN ISO 12944-5 C5M and C5I protecting paint system grades.

Closed Impeller

UCL Closed impeller

This type of impeller is meant to process clean media only. They’re very efficient, and you won’t have to think about recirculation.

Semi-Open Radial Impeller

UCL semi open radial impeller

This type of impeller can process media with high concentrations of solids. However, compared to the closed impeller, you’ll get less hydraulic efficiency, and there will be recirculation.

Typical Applications

The UCL/UCL-B Series is ready to handle your most aggressive, hazardous and corrosive materials with a low viscosity in any industry setting. With some of the most consistently durable bearing brackets on the market, you can be sure these pumps will perform even in heavy-duty operations.

The hydraulic design of these models focuses on catering to the needs of the chemical industry, and due to their stringent guidelines, the pumps will make an excellent choice for those working in these industries:

  • Farming, including fertilizer and pesticide processing
  • Basic and complex chemical processing
  • Wastewater and air treatment
  • Pharmaceuticals and other medicine-related fields
