Diaphragm Pumps

ARO's ATEX-certified diaphragm pumps are widely used to pump various light to medium viscosity fluids in chemical processing industries and water / wastewater treatment plants. These ARO pumps feature an unbalanced valve design that eliminates the occurrence of valve centering and pump stall-out even when the inlet pressure is very low. The company manufactures metallic and non-metallic electric diaphragm pumps in different sizes, operating pressures and diaphragm materials.

Air Operated Diaphragm Pumps

Air operated diaphragm pumps are designed to pump thick slurries & solid-laden liquids in applications such as dewatering and mining. Raptor Supplies offers a wide range of air operated diaphragm pumps from brands like Aro, Sandpiper, Flojet, Versa-Matic. Standard-duty Sandpiper air-diaphragm pumps are ideal for dewatering & pumping slurries, solvents, abrasive fluids, weak acids & suspended solids in petrochemical and food processing plants. These pumps are designed to operate on a continuous supply of compressed air and feature aluminium / cast iron / stainless steel / non-metallic construction to ensure structural rigidity. The brand's self-priming double-diaphragm pumps feature ball check valves for withstanding consistent fluid flow and connecting rods for reliable & consistent diaphragm control. These all-bolted, shear-sensitive air diaphragm pumps are offered in flange and NPT connection styles. Air-operated double-diaphragm pumps from Versa-Matic are ideal for easy & safe transport of chemicals & other fluids. These diaphragm pumps feature leak-free bolted construction for superior chemical resistance, with multi-position foot mounts & multiple ported manifolds offering installation flexibility. They can withstand temperatures up to 275 degrees F and have operating pressures ranging between 100 & 125 psi. Raptor Supplies offers a wide range of air operated diaphragm pumps in heights ranging from 10-3/64 to 16-61/64 inches.

Frequently Asked Questions

Can these pumps be used for metering or dosing application?

Yes, they can be used for metering. For precise dosing, accessories like pulsation dampeners and stroke adjustment controls may be required.

How to maintain these air operated diaphragm pumps?

Routine maintenance includes inspecting diaphragms for wear, checking valves, and tightening connections. Lubrication may be necessary, depending on the pump design.

Can these Sandpiper pumps be used in dry run situations?

These AODD pumps can be safely dry-run and deadheaded without causing any damage to the pump or system.

What is the maximum suction height that these double diaphragm pumps offer?

Sandpiper pumps can continuously pump fluids even if situated out of the pit and offer a maximum suction lift of 9.8 m.
