Richter Vortex Pump - PFA PTFE Lined Magnetic Drive Mechanical Seal Solids Handling

Richter Vortex Pumps with Magnetic Drive or Mechanical Seal

Richter Vortex Pumps are fluoroplastic-lined centrifugal pumps with a semi-open recessed impeller design, specifically engineered for handling solids-laden, crystallizing, fibrous, and shear-sensitive corrosive fluids. Available with sealless magnetic drive (MNK-X series) for zero-emission applications or RG4 SiC mechanical seal (SCK-X series), these pumps use a vortex flow principle where the impeller sits behind the volute, preventing direct contact with solids and ensuring clog-free operation.

Manufactured by Richter Chemie-Technik GmbH, Germany, the vortex variants are based on the proven MNK and SCK platforms with a specialized semi-open vortex impeller. Because the impeller is recessed and does not directly contact the pumped fluid, it handles suspended solids, crystals, fibers, and shear-sensitive chemicals without clogging, impeller damage, or product degradation. With PFA or PTFE lining, SAFEGLIDE PLUS bearings, ATEX certification, and temperatures from -60°C to +200°C, Richter Vortex Pumps provide the ideal solution for the most challenging corrosive-abrasive fluid applications.

Key Features & Advantages

Recessed Vortex ImpellerSemi-open impeller sits behind the volute, creating vortex flow that handles solids without impeller contact — prevents clogging and impeller wear
Solids & Slurry HandlingPasses suspended solids, crystals, fibers, and abrasive particles without clogging or damage
Low Shear PumpingVortex flow generates significantly less shear than conventional impellers — ideal for shear-sensitive chemicals, polymers, and biological fluids
Crystallizing MediaHandles crystallizing and precipitating fluids that would block conventional pumps
Magnetic Drive Option (MNK-X)Sealless design for zero-emission containment of hazardous solids-laden fluids
Mechanical Seal Option (SCK-X)RG4 SiC seal for higher flow requirements with solids-laden media
Fluoroplastic LiningPFA, PTFE, and conductive PFA provide exceptional chemical and abrasion resistance
Wide Temperature Range-60°C to +200°C for diverse process conditions
ATEX CertifiedCompliant with EU ATEX Directive 2014/34/EU for explosive atmospheres

Frequently Asked Questions

What is a vortex pump and how does it work?

A vortex pump uses a semi-open recessed impeller that sits behind the volute, creating a vortex flow pattern that draws fluid through the pump. Because the impeller does not contact the pumped fluid directly, it can handle solids, fibers, crystallizing media, and shear-sensitive fluids without clogging or product degradation.

The MNK-X uses a sealless magnetic drive for zero-emission containment, ideal for toxic and hazardous solids-laden fluids. The SCK-X uses an RG4 SiC mechanical seal, preferred when higher flow rates are needed or when process conditions make magnetic drive impractical. Both use the same vortex impeller design.

Vortex pumps excel at handling fluids containing suspended solids, crystallizing or precipitating chemicals, fibrous materials, slurries, shear-sensitive fluids, and any media that would clog or damage a conventional closed-impeller pump.

Yes. Because the recessed vortex impeller does not directly contact the pumped fluid, it generates significantly less shear than conventional centrifugal impellers. This makes vortex pumps ideal for shear-sensitive chemicals, polymers, and biological fluids where product integrity must be maintained.
