The basis of any Progressive Cavity Single Screw Pump is a power section which usually consists of a metal rotor (n-start external helix) and a rubber stator (n+1-start internal helix). Rotation of the rotor inside the stator creates sealed cavities that progressively move from suction to discharge side of the pump producing differential pressure.

The substitution of gerotor single screw pair

Specialists of SOLTEC ® company Novomoskovsk Mechanical Plant fulfill any tasks given by a Customer. It means the installation of SOLTEC ® gerotor pair on the unit of import manufacture. This pump transfers the sludge of sewage on one of the Moscow water canal. That’s why the abrasive elastomer is added to the stator designing and rotor is made of steel 40X13 with thermal treatment.

An original pitch ratio for fastening to the existing flexible joint was designed while implementing the order. SOLTEC ® company Novomoskovsk Mechanical Plant has executed many times such tasks for different pumps. It proves high technological potential function of the company and high level of Customer’s confidence to it.
