The Benefits of a Twin Screw Pump: QTS Series by Q Pumps

Posted on by Sara Springer

Do you need a positive displacement pump for your project but aren’t satisfied with how it handles your materials? It’s time to consider a Twin Screw Pump by Q Pumps to improve your manufacturing process and find a solution for your material handling challenges.

What makes a twin screw pump different from other positive displacement pumps? It traps the fluid in a cavity generated by the helical geometry of the twin screw-type rotors. This cavity with fluid is displaced and expelled, generating the pumping action. The rotors are synchronized not to have contact with each other, creating gentle pumping of fluids. These positive displacement pumps are ideal for food, beverage, pharmaceutical, and personal hygiene industries.

Want to know more? Here are additional characteristics of Q Pumps® Twin Screw (QTS) pumps:

  • Self Priming. Can expel trapped air both in the suction pipe and inside its body and discharge the liquid to be pumped again, without the need to be primed before washing.
  • Made of 100% stainless steel, wet parts in SS 316L.
  • Speed up to 3,000 rpm (depending on product viscosity).
  • Very tight tolerances for vacuum capacity.
  • 3 types of seals: mechanical, o-ring, & lip.

There are also many advantages of installing a twin screw pump into your system, including the following:

  • Pulsation free.
  • Handling soft suspended solids u to 38mm/1.5″ without damaging them.
  • 100% CIP at high and low speeds.
  • Constant flow, and gentle fluid handling.
  • Self-draining and self-priming.
  • Excellent handling of abrasive products, the rotating movement facilitates the rapid release of trapped solids, thus reducing abrasive wear.
  • No contact between the rotor and casing working at high pressures.
  • Silent.
  • Less chance of cavitation.
  • No dead zones.
  • Bidirectional: reversible, makes possible the recovery of product from the line.

The QTS Pump line by Q Pumps® also meets sanitary standards and has been certified by several global associations. Please get in touch with the manufacturer for full details. Contact SPRINGER PUMPS® today to learn more about Q Pumps’ Twin Screw Pump Line (QTS) or to request a quote.

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.
