Sandpiper heavy duty flap pumps for tough solids

Mar. 15, 2018 – Brampton, Ontario-based York Fluid Controls has recently began distributing Sandpiper’s Signature Series line of air-operated double-diaphragm (AODD) pumps, which includes a variety of Heavy Duty Flap (HDF) pumps designed to handle solid materials and abrasive slurries with better suction.

Each Sandpiper HDF pumps includes a bottom discharge that allows solids to pass through and prevents them from settling inside. Flap check valves also assist in handling large solids. These HDF pumps are capable of handling up to 76 millimetres of solids, with a maximum suction lift of seven metres. Available in six designs, the HDF pumps have walls constructed of sand-casted aluminum, cast iron and stainless steel, with elastomer diaphragms and check valves. Other features include: durable diaphragm connecting rods for diaphragm control; externally serviceable air distribution systems with air valves; and dry primes for up to seven metres of water. Sandpiper describes the HDF pumps as lightweight and portable, with some weighing as little as 21 kilograms. Flow rates range from 159 to 988 litres per minute, depending on the design.
