The Compact pump is based on the Moineau™ progressing cavity pump principle. The Compact cast iron progressing cavity pump is ideal for small space requirements. Instead of the connecting rod, used on the conventional progressing cavity pumps, the Compact PCP is designed with a floating stator in elastomer without frame. The flexibility of the stator allows the rotor to rotate eccentrically, as the rotor is directly connected to the drive. The pump body is consequently shorter.
