Type KL-RS
Hopper feed pump

Very robust hopper silo pump with a large viscosity range and particularly good flow rates

Hopper feed pump Type KL-RS

Pumps of the WANGEN KL-RS series are hopper silo pumps for conveying and dosing dewatered sewage sludge with a high-solids content (DS) of 15% to 45%. These features make silo discharge pumps of the type KL-RS an indispensable core aggregate in modern sewage treatment plants.

WANGEN PUMPEN's quality promise: Extremely robust and reliable pumps, designed for extra long lifepan.

Fields of Application

The WANGEN KL-RS hopper silo pump series processes media with a wide range of viscosities and delivers a good flow rate, even with media containing abrasive and fibrous additives.

The slide valve design at the end of the hopper tunnel allows inspection and monitoring work of the hopper - without the need to disassemble the pump. Also, gate valves allow the rotors / stators to be exchanged, even if the silo is full.
