Weir Specialty Pumps, Wemco Division, Makes the World’s Best Screw Centrifugal Pumps.

The Wemco Hidrostal Pump Line.  These Pumps Feature a  Unique Clog Free Design with Efficiencies Up to 80%.  The Hidrostal’s screw/centrifugal impeller with open channel design combines the clog-free features of a vortex pump, the gentle action of a screw pump, and the high efficiency of a centrifugal pump.

Features & Benefits:

• High efficiency – smooth flow, and low turbulence produced by the screw/centrifugal impeller keep hydraulic losses to a minimum. The result is pumping efficiency unequaled by any other “clog-free” pump.
• Clog-free operation – No blockages mean minimum attention and minimum maintenance.
• Gentle action prevents damage to delicate solids.
• Low NPSH requirements help keep thick sludges and large solids moving as available suction head decreases.
• Positive suction flow enables pump to handle thick sludges.
• Abrasion resistant construction with 550 Brinell High Chrome Iron impeller and externally adjustable suction liner available.

Example Applications:

• Pumping Delicate Products Without Damage.
• Thickened Tomato & Fruit Pastes.
• Clogging Solids like Tomato Skins and Stringy Materials.
• Evaporator Circuits.
• Flume Systems.
• Fluids that cannot be Emulsified.
