A Primer On Twin Screw Vane Pumps (Vickers V10/V20)

Vickers Twin Screw Vane Pumps (V10, 20, 25 and 30)

Vickers Twin Screw Vane Pumps (V10, 20, 25 and 30) are ruggedly built to handle corrosive and abrasive fluids, as well as high viscosity materials. They have a wide range of applications including chemical processing, food and beverage, mining and power generation industries.

The Vickers twin screw pumps are available in several configurations. The most common is the V10 with an operating range up to 600 psig (4.14 MPa) @ 300 rpm. This pump has a maximum head of 120 feet (36.5 meters). Another popular configuration is the V20 which operates up to 1,000 psig (6.89 MPa) @ 300 rpm with a maximum head of 180 feet (55 meters). Both models are available in both self-priming or non-self priming configurations with either flanged or bolted discharge connections.

The V20/30 model has an added feature called a check valve which prevents backflow into the suction side of the pump during shutdown conditions such as power failure or when changing direction on startup. This check valve is located between the motor and gear box assembly and allows for easy removal for maintenance purposes without disassembling entire unit

A Primer On Twin Screw Vane Pumps (Vickers V10/V20)

The Twin Screw Vane pumps (Vickers V10/V20) are a type of positive displacement pump that is used in the chemical, petrochemical and pharmaceutical industries. They are also used in water treatment, food processing and power generation applications.

The twin screw vane pump is a positive displacement device that utilizes two helical screws to generate pumping action. It can be designed with various numbers of stages and axial pitches. A stage consists of two consecutive helical screws, while an axial pitch refers to the distance between two successive helical threads.

The twin screw vane pump has several advantages over other types of pumps such as centrifugal pumps which are used for high pressure applications. It has a high volumetric efficiency, low noise levels and low maintenance requirements. In addition, it’s compact size makes it easy to install in tight spaces without compromising on performance or reliability.

Dynamic Pumps

The twin screw vane pump is another type of positive displacement pump, where the fluid is pumped by the rotation of two screws. The screw has a helical blade that rises and falls in the bore as it rotates.

In a twin screw vane pump, the fluid enters at one end and flows around the blades of both screws, entering and leaving through a single port. The screws are positioned on either side of a central shaft so that as one rises, the other falls. As one blade pushes fluid out of the bore, another blade sucks fluid into it creating positive displacement within the pump case. The two screws rotate in opposite directions which creates increased pressure within the pump chamber.

The twin screw vane pump is used in low viscosity fluids such as water or steam where high pressures are required over small flow rates or where high volumetric efficiencies are required over wide ranges of flow rates.
