Yamada® NDP-25 Series Pump

Constructed with flanged connections, end manifold, and non-metallic center body. Bolted construction helps eliminate leaks and simplify post-maintenance reassembly. Outside-accessible air valve allows for maintenance without taking the pump out of service. Uses a completely, non-lubricated main air valve and independent pilot mechanism to control air logic. Slightly depressed area by the inner center disk creates a pressure drop at the end of the air valve to permit shifting.
