    • Overview

    Diaphragm pumps are positive-displacement pumps that use a flexible diaphragm to move fluids. They handle viscous, abrasive, shear-sensitive and solids-laden liquids, making them common in chemical processing, wastewater, mining and construction. Air-operated double-diaphragm (AODD) and mechanically driven models offer self-priming, dry-run capability and good suction lift. Select housing and elastomer materials for fluid compatibility, and size by flow, discharge pressure and cycle rate for reliable performance.

    FAQ

    What should I check when buying a used diaphragm pump?
    Inspect diaphragms, check valves and seats, examine housings and fasteners for corrosion or cracks, verify air motor or drive condition, review service records, and confirm spare-part availability and material compatibility with your fluid.
    How do I ensure safe shipping of a diaphragm pump?
    Drain and clean the pump, cap ports, secure moving parts, brace or crate the unit on a pallet, label any hazardous residue, and use a carrier experienced with industrial pumps. Insure the shipment and document condition before transit.
    What maintenance should I plan after purchase?
    Perform daily visual checks for leaks, monthly tightness and air system inspections, and replace diaphragms and valve parts on a schedule based on operating hours/cycles. Keep a spare diaphragm/valve kit and follow the manufacturer’s lubrication and inspection guidance.
