Deskripsi
Sandpiper BEAST SPB30/SPB40 3"/4" AODD Pump Flap Valves for Cast Iron Pumps
Genuine Sandpiper flap valve replacement parts for compatible BEAST SPB30/SPB40 3"/4" Cast Iron AODD pumps. Pump construction identifies the compatible pump configuration; the flap valve material is selected separately from the manufacturer-listed options below.
The Sandpiper BEAST SPB30/SPB40 flap valve is the moving wet-end check-valve component used in compatible flap-valve AODD pumps. It opens away from the flap valve seat to allow forward fluid movement and closes against the seat to restrict reverse flow. Select the replacement by exact pump model, pump construction, flap valve material and Sandpiper manufacturer part number.
Product Overview
The Sandpiper BEAST SPB30/SPB40 flap valve is intended for servicing compatible 3"/4" Cast Iron flap-valve AODD pumps.
The flap valve and its mating seat work together as a one-way wet-end check valve. The flap valve is the moving replacement component; the flap valve seat and related hinge, wear, retainer or sealing components are separate parts where Sandpiper lists them separately.
Manufacturer-listed flap valve selections for this product include Buna, Neoprene, Santoprene, Hytrel, Urethane. Select the exact material and manufacturer part number for the installed pump. Do not select the flap valve from nominal pump size or diaphragm material alone.
