Sludge Progressing Cavity Pumps - K range

As sludge transfer pumps, the K range is high performance industrial progressing cavity pumps. This PCP, available in block or long coupled configuration, can be manufactured in different materials including cast iron, stainless steel 304 and 316 as well as Duplex and super Duplex steel (SAF 2205) in order to suit highly corrosive and difficult applications (high salinity laden liquids for example). This pump is also suited for general industry, wastewater, oil & gas and marine applications.

As the pin joint system is a critical part for any progressing cavity pump, Sydex has designed its own pin joint to ensure extremely long service life and provide a 2 years warranty for this system.


Firstly, by maximising the length of the coupling rod, we have ensured that the angular motion is kept to a minimum [less than 0.5 degrees]. Indeed, the less the angular motion, the less the forces and loads on the rotor end, and the pump drive shaft. This significantly extends stator life, and ensures the mechanical seal is not adversely affected by shaft deflection.


Many of our K range progressing cavity pumps use a 4 pin joint system, unlike our competitors who use only 2. By using this system, we are able to supply the coupling rod as a complete pre-assembled kit, making assembly and maintenance a simple task. The pin joint is securely sealed with an elastomer cover, and protected by a metallic sleeve. The joint is oil-lubricated ensure excellent heat dissipation.
