Hastelloy-C Gear Pump - SM935 M
CHEMSTEEL™ pumps are designed to handle 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.
Additionally, CHEMSTEEL™ pumps offer bi-directional operation for applications requiring reversing flow.
Compartir
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 metallic 316 stainless, W88 stainless and Alloy C. Also inPolytetrafluoroethylene, polyphenylenesulfide and polyetheretherketone.
- Shafts are 316 stainless steel or Alloy C.
- Bearings available in Carbon and Polytetrafluoroethylene.
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 450°F. 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.
MAINTENANCE
A three-part housing provides easy disassembly and service. Full size bearings match the gear diameter, and eliminate the need for separate wear plates. TFE encapsulating silicone o-ring pump housing seals provide elastic memory to assure an effective long lasting seal and thus avoiding the re-torqueing required of pumps using pure TFE.
To order a CHEMKIT™ parts kit, simply add a “K” to the end of the model number.
A repair kit contains the following parts: bearings, gears, o-rings, shafts, keys, c clips, and retaining ring.
LIFE CYCLE/COST OF OWNERSHIP
Pump design and materials selection, together provide the longest life available from a gear pump.
Key attributes include:
