INOXPA DHC Twin Screw Pump


The INOXPA DCH is a twin-screw pump, with hygienic design, suitable for use in the food, dairy, beverage and cosmetic industries.

The flow is uniform and in an axial direction, so there are no changes of volume or physical properties of the product. Therefore, it is an ideal pump for handling shear-sensitive fluids. It has a high suction lift capability with very low NPSH values. It is capable of pumping liquids with high viscosity, but also with low viscosity, so it can be used as a CIP-supply pump.

The design ensures a full cleanability and drain-ability.


The INOXPA DCH pumps are available in two versions: close-coupled and bare shaft construction. Having a three-part design (suction casing, discharge casing and separate flange) to dismantle the pieces more easily, and designed according to the EHEDG recommendations. The mechanical seals have a hygienic design and when required, other materials can be used.

Positive Displacement Pump Problems?

New Type of Positive Displacement Pump Solves Common Issues

Qts Gif Loop Red Balls

Positive displacement pumps are used successfully in a wide range of applications in almost every industry. Many of these applications, however, suffer from a wide range of problems common to pumps like rotary lobe, rotary piston and progressive cavity pumps. Whether it be cavitation, rotor-to-body contact, wear due to tight clearances and abrasive fluids, loud operating noise or frequent repairs due to axial deflection, these issues cause no end of headaches to the plant maintenance personnel that deal with them.

Enter in the QTS Twin Screw pump. Twin screw pumps solve many of these problems. Due to the inherent qualities of the pump design they rarely produce cavitation (low NPSH requirements), there is no body/rotor or rotor/rotor contact (even at high pressures), abrasive fluids don’t cause nearly as much wear, they operate at very low noise levels and have absolutely zero axial deflection. QTS Twin Screw pumps are the future of positive displacement pumping.
