Sandpiper - 2" Non-Metallic Flap Valve Pump - NEW

Features & Specifications:

Sandpiper is pleased to announce the release of the new HD20F 2” Heavy Duty Non-Metallic Flap Valve pump which has been designed to solve the most common problems in mine dewatering, sump, and chemical transfer applications, and is ideal for pumping corrosive fluids.  Its robust, yet lightweight design of 53 lbs. allows for ease of movement for those applications requiring portability. 

The SANDPIPER signature flap valve design handles suspended and non-suspended solids up to 1.8” (46 mm), and with top suction and bottom discharge configuration, possible damage due to settling solids is virtually eliminated. This unique pump has been engineered to fully function in any position, includes lifting handles, hanging points, and has durable mounting feet for use in static or mobile applications.  With best-in-class flow rates of 150 GPM (567 lpm), and suction lift of 20 feet (6.1 m), the HD20F delivers the performance and flexibility our customers and markets demand. 

For ease of maintenance, the ESADS+ Plus externally serviceable air valve system is used, and this new product also provides easy access to flap check areas.  This design allows for complete in-line inspection or repair without removing the pump from its location, saving time and effort.  These features make it the ideal solution for numerous applications.
