SEEPEX SCT Progressive Cavity Pumps

Sep 21, 2023 | Seepex

YOUR DOWNTIME SOLUTION. Are you tired of costly maintenance and extended downtime? With SEEPEX #SmartConveyingTechnology (SCT), say hello to quicker maintenance, increased efficiency, and significantly reduced life cycle costs. SEEPEX SCT progressive cavity pumps offer:

✅ 200% extended maintenance intervals
✅ 85% reduced maintenance time
✅ 200% longer stator life
✅ 25% energy saving compared to conventional PC pump design

Additionally, SCT is available as a retrofit option for all compatible pumps, making it even easier to upgrade your system.

SCT – SMART CONVEYING TECHNOLOGY

CONTINUOUS ONGOING DEVELOPMENT

The patented Smart Conveying Technology (SCT) ensures the fastest maintenance possible resulting in reduced downtime and significantly reduced life cycle costs in virtually all market sectors. The Smart Stator and Rotor are both manufactured in two pieces allowing the pump to be maintained without the need to remove either the suction or discharge pipe work resulting in an 85% reduction in maintenance times.

The unique design of SCT enables the sealing line between the rotor and stator to be adjusted to suit the required application and also to compensate when wear starts to occur, typically resulting in more than doubling the life of the rotor and stator.

Conveying Capacity: 0.3–134 m³/h; 1.3–590 US gpm

Pressure: ≤ 8 bar; ≤ 120 psi

Reduced downtime

Reduction in maintenenance time by up to 85%

Increased service life

Integrated retensioning device resulting in up to 200% increase in the life of the rotor and stator

Maintain in Place

Two-piece Smart Stator and Rotor allow the pump to be maintained in place without the need to remove the suction or discharge pipe work or the use of any special tools

Increased productivity

High energy and performance efficiency due to the in-built retensioning device which allows the the clamp between the rotor and stator to be adjusted for optimum performance

Environmentally friendly

Free molded stator halves can be easily recycled due to the lack of the stator tube.
Replacment of the rotor does not require additional universal joint components or lubricants

Retrofit-Option

The SCT Retrofit-Kit allows an existing conventional tube stator pump to be upgraded without the need to modify the pipework or base plate

Ease of installation

As SCT pumps do not require any pipework to be removed during maintenance, additional ‘spool’ pieces are not required to be fitted reducing installation costs and overall footprint

Pump Systems – Smart Air Injection (SAI) – The impulse for pilsner and grain

Sep 1, 2021 | Seepex

Smart Air Injection is a customized SEEPEX system solution. The innovative combination of progressive cavity pumping and compressed air conveying results in a low pressure level in the pipe – optimal for a long service life and lower investment and operating costs. In the food industry, SAI is used in breweries and distilleries to convey hop and malt spent grains by means of controlled compressed air impulses.

Progressive Cavity Pumps in Chemical Metering for Wastewater Reclamation Plant

Oct 17, 2019 | Seepex

The wastewater treatment process requires precise and efficient dosing of a variety of harsh and corrosive chemicals. Diaphragm and peristaltic metering pumps are typically the go-to technologies for this type of application. However, for one water reclamation plant in Cape Coral, Florida, progressive cavity pumps (PCPs) were selected for their precision, efficiency and reliability of its sodium hypochlorite dosing system.

First EHEDG Type EL Class 1 Certification Certified Progressive Cavity Pump

Dec 6, 2018 | Seepex

Once again, SEEPEX is leading the way in the technical development of progressive cavity pumps. SEEPEX is the first manufacturer to offer a newly developed progressive cavity pump, which is certified according to the new EHEDG testing process and given Type EL Class 1 certification.

Thus, the new BCFH range meets the highest requirements with regard to hygiene, cleaning and sterilization, and ensures gentle conveying. The new, much more transparent certification process will be made compulsory for all components with EHEDG certifications by 2020. Above all, this includes components in production facilities in the food and beverage, cosmetic and pharmaceutical industries.

Certified Cleaning Capability

The Weihenstephan Hygienic Design Institute has confirmed the residue-free cleanability of the BCFH range with its dead-space-free rotating unit by carrying out the “EHEDG in-place cleanability” test. This test of the Clean in Place (CIP) feature for components involves checking for the presence of bacterial endospores after completing the standard in-place cleaning. The CIP flushing cleans the pump without leaving any residue, which does not require the disassembly of components or additional manual cleaning.

Residue-Free Cleaning and Even Easier Maintenance

All SEEPEX hygienic pumps are designed with a special surface shape and dead-space-free pump housing, so that no product components are able to collect there. The new BCFH pump is distinguished by its partitioned suction casing, which is very easy to clean. The suction line does not need to be disassembled for maintenance of its rotating unit or mechanical seal. The flushing inlet has been placed outside the center, in order to optimize the turbulence of cleaning agents. Its new inlet geometry causes flushing fluid to flow even better throughout the pump.

Top Technical Performance – Titanium Shaft Picks Up Rotation

Another main feature of the new BCHF range is a rotating unit made of titanium, the Flexrod, designed to be corrosion-resistant, low maintenance and wear-free. Since the Flexrod gently picks up eccentric motion and passes it on to the rotor, it does not need any joints. Fewer components in a hygienic pump offer even more cleaning advantages. The Flexrod is detachable from the rotor and plug-in shaft, which enormously simplifies maintenance.
