Pump Features:

Compact, solid design - minimal space required
Pumps move everything from water to very viscous materials with solids
Sealless - are environmentally friendly, no seals or packing to leak
Safe in hazardous areas - air driven - non sparking
Can run dry without damage
Self-priming to over 8 meters
Variable flow - simply regulate the inlet air supply to adjust the pump flow from zero to max flow
Pump stalls if discharge is closed and restarts when discharge is opened (no heat build-up, or wear)
Composite, long life diaphragms for heavy duty applications (no diaphragm discs). Surface of diaphragm is smooth and not interrupted by any seals whatsoever
Operates without any lubrication
Easy maintenance

Pump Materials:

Polyethylene, PTFE, PE conductive, PTFE conductive
Aluminum, aluminum coated with PTFE
