SolidPRO™ Pump for Solids Handling
with "Flapper Valve" technology
Yamada's SolidPRO™ Pump is designed to pump fluids containing solids up to 2 inches (50mm) in diameter. Built on the foundation of the NDP-Series line of pumps, the SolidPRO incorporates Yamada's patented Stall-free/Lube-free Air Valve and rugged, easy-to-service bolted construction.
Designed for durability in the field, the SolidPRO's innovative flap-type check valve technology provides streaming passage of solids while minimizing clogging and downtime. Four external bolts release valve covers on either side permitting service and maintenance without removing the pump from installation.
