MODEL ST1/ST25 Performance Curve
Performance based on the following: elastomer fitted pump, flooded suction,
water at ambient conditions. The use of other materials and varying hydraulic
conditions may result in deviations in excess of 5%.
SANDPIPER® Containment Duty Pumps: Sealless Safety
This pump is part of the Containment Duty Pumps. It is specially fitted with PTFE diaphragms as well as elastomeric or elastomeric/PTFE driver diaphragms. The liquid-filled
spill chambers provide an additional chemically-resistant barrier, should a pumping diaphragm fail. The Spill Containment design gives the pump user advanced warning of
diaphragm failure, before pumpage can damage the air valve or be released into the work environment. Three optional leak detectors available for this model:
• Mechanical VIP Leak Detector* 031-025-000 • Electronic Leak Detector* (115V) 032-043-000 • Electronic Leak Detector* (220V) 032-043-000
The Containment Duty pumps offer many different levels of materials and spill monitoring devices designed to fit a variety of applications and budgets.
* Leak Detectors are not ATEX Compliant
