Oberdorfer S2141Fpc SS Pump SS/Tf Grs Cbn Brg
CHEMSTEEL™ pumps are designed to handle common and highly corrosive liquids that must be pumped under pressure. Manufactured to extremely precise tolerance, the CHEMSTEEL™ pump line prevents system contamination while maintaining the purity and integrity of the liquid being pumped. Its rugged, three-section, O-ring sealed thru-bolt construction provides ease of servicing and parts replacement. Helical gearing offers noise reduction by as much as 10db, while the tandem pumps double the output flow for a single fluid, or with isolation, handle other fluids in direct ratio to the first Additionally, CHEMSTEEL™ pumps offer bi-directional operation for applications requiring reversing flow.
FEATURES
Gear/bearing design allows for “trimming” for optimizing the pump’s maximum flow to reach minimum turndown or to match flow to a specific OEM’s requirement.
Special materials combinations are available for specific liquids:
Stainless or Alloy C housing construction.
Gears available in 316 stainless,. W88 stainless and Alloy C. Also in Polytetrafluoroethylene, polyphenylenesulfide and polyetheretherketone.
Shafts are 316 stainless steel or Alloy C.
Bearings available in carbon or polytetrafluoroethylene.
Full range of seal options including lip seal, packing and mechanical designs.
DRIVE
The pump is driven directly from the electric motor shaft by means of a flexible coupling. A close-coupled adapter connects the pump to the motor.
LIQUIDS & TEMPERATURES
This pump is suitable to handle clear lubricating and non-lubricating fluids at temperatures to 450F. These pumps will handle viscous fluids to 100,000 cps (462,000 SSU) at reduced shaft speeds.
SUCTION LIFT
This pump has a suction lift capability of 20 feet for a new pump. Though gear pumps are self-priming, a foot valve is recommended. If possible, wet gears with the liquid to be pumped for the first dry start. Liquid retained in the system and gear chambers serves to wet the pump on subsequent starts.
