Product Details
Product Overview
The pneumatic diaphragm pump uses two diaphragms driven alternately by compressed air. Because air pressure does the work, the pump can run dry, self-primes and passes solids without a valve in the flow path.
Structure and Key Features
- Pump body in cast iron or stainless steel with standard flange connections.
- Closed or open impeller, dynamically balanced for smooth running.
- Mechanical seal or packing selected by media temperature and cleanliness.
Specifications and Selection
Confirm air pressure and consumption, port size, diaphragm material and solids size before selection.
Applications
Chemical transfer, slurry and sludge, paint and solvent handling.
