two stage self priming pump

The Gorman-Rupp VS3B60-B is a unique two-stage self priming wastewater pump, and offers up to twice the pressure of most other solids handling self priming pumps. The compact staging is accomplished by the addition of the patented Ultra Mate® 2nd stage to the V3B60-B single stage pump via an innovative transition chamber that reduces the friction losses normally associated with staged pumping. The VS3B60-B will handle a 76mm spherical solids, and because of its patented “self cleaning wear plate system”, is able to handle stringy materials, such as rags. This makes them ideal for pumping raw sewage or at the wastewater treatment plant.

The VS3B60-B  (Two Stage Self Priming Pump) is also a good choice for high head industrial wastewater applications because it is a self priming pump and can be mounted “high and dry” above the wastewater, making it safer for operators to access for monitoring and servicing. Blockages are also easily handled because the pumps are mounted at surface level and easily accessed. A large removable inspection cover-plate gives quick access to pump internals. This feature makes them ideal for a sewage pump station. No cranes or confined spaces issues for blockage removal or routine maintenance. If the water is corrosive and/or abrasive, wearing parts can be supplied in Hardened Iron, 316 grade stainless steel or duplex stainless steel [CD4MCu].

The VS3B can re-prime a suction lift of 7.6m with a completely dry suction line and only a half casing full of water, making it ideal for continuous, automatic, unattended operation. The VS3B has a 100mm suction port and an 80mm discharge port and is capable of flows to 40 l/s and heads to 65m.
