SPX FLOW Universal 3 Series positive displacement pumps

SPX FLOW has released a series of positive displacement (PD) pumps, the Universal 3 Series, from its Waukesha Cherry-Burrell brand.

The pumps are 3-A certified and can be cleaned in place as standard. Connection of the rotor and shaft is completely sealed from the product zone to prevent any contamination and reduces the risk of internal corrosion. The front-loaded seals are easy to maintain, reduce maintenance times and are available in a choice of materials and types, including single and double mechanical and O-ring versions to suit a wide variety of process applications. The pumps further provide the versatility of bidirectional flow capability and 3-way mounting for easy integration into process systems.

Designed for operating up to 500 psi (34.5 bar) pressure and 149°C temperature as standard, the pumps offer customers robustness for long-life operation. The values vary depending on the pump size and rating option. Key features include a heavy-duty stainless steel frame, double tapered bearings, positive lubrication of bearings and the use of a wave spring to extend outer seal life. Shorter, large diameter shafts made from 17-4PH stainless steel reduce overhung loads, improve seal life and provide greater torque capacity, which enables the pumps to be used in higher pressure applications.

Close running clearance rotors reduce slippage and add benefit in terms of improved sanitary performance and longevity. Combined with a long sealing path from inlet to outlet, the pump is further designed for low slip operation, high efficiency, good priming capability and effective flow control.
