AxFlow launches new twin-screw rotary positive displacement pump
Pump specialist AxFlow has added a new rotary positive displacement pump to its portfolio, the ‘twin-screw’ Waukesha Universal TS.
The new pump uses Waukesha Alloy 88 non-galling material twin screws to pump various media containing large particulates, in turn lowering damage to the pump and reducing the need for maintenance. According to a statement from AxFlow, the new pump also offers a high suction capability and wide range of operating speeds, meaning that only one pump is required to transfer product and undertake CIP.
By reducing the number of pumps, valves and control instrumentation required, the Waukesha is designed to contribute towards reduced costs, and facilitate simpler, more compact systems.
The rotating geometry of the twin screws creates a pulse free flow, making the pump suitable for a range of applications such as feeding homogenisers. The meshing screws have identical rear and front profiles, giving bi-directional flows which can contribute towards easier media transfer between vessels without the need to alter the pump setup. Meanwhile, a design featuring front loaded access to product side seals aims to enable easy maintenance and reduced downtime.
The Universal TS is available in four models each with three screw pitch options, and delivers flows of up to 4,618lt/min and has a pressure range up to 25bar.
