FAQs

What is a diaphragm pump and how does it work?

A diaphragm pump is a self-priming pump that uses a flexible diaphragm to draw in and discharge fluid. The Santoprene diaphragm moves back and forth, separating the fluid from mechanical parts – perfect for sludge, slurry, and viscous fluids.

AMT diaphragm pumps are durable, low-maintenance, and built for demanding conditions. With a lightweight sand-cast aluminum housing and thermoplastic diaphragm, they combine strength with efficiency.

The AMT series offers three drive options: Gasoline diaphragm pump – powered by a Honda GX engine for maximum independence on remote sites. Electric diaphragm pump – quiet, emission-free, and ideal for indoor or urban use. Battery-powered diaphragm pump – fully portable with a lithium-ion battery for flexible operation anywhere.

Electric pumps provide silent, emission-free performance. Gasoline models deliver high mobility and power where electricity isn’t available. Battery-driven pumps combine both: mobile, quiet, and emission-free.

All AMT diaphragm pumps feature up to 6.1 m suction lift and 7.6 m discharge head, ensuring reliable pumping even from deep or uneven locations.

Yes. AMT diaphragm pumps can handle solids up to 41 mm, making them ideal for pumping sludge, slurry, and wastewater.

Yes. Their modular design simplifies cleaning and servicing, minimizing downtime and keeping performance consistent.

Accessories include suction and discharge hoses (Storz or Perrot couplings), strainers, engine oil, and battery chargers for the battery-driven models.

AMT diaphragm pumps are ideal for construction site dewatering, wastewater treatment, industrial fluid handling, and emergency pumping.

The 2” diaphragm pump provides up to 11 m³/h flow for compact setups, while the 3” diaphragm pump handles 20 m³/h and larger solids. Your choice depends on the required flow and application.
