The NGP-7055-S is a single piston, double-acting hydraulic pump designed for precision liquid application in agricultural settings. It offers a compact and cost-effective solution for variable rate piston pump drives, allowing for quick and stable adjustments to application rates within milliseconds. The pump maintains consistent application rates regardless of temperature fluctuations, ensuring reliable performance. Users have the option to supply their own SAE A 2-bolt motor, or they can opt for a hydraulic motor/PWM manifold kit available from John Blue Company. The pump features a 1-1/2″ female pipe thread (FPT) inlet and outlet, facilitating easy integration into existing systems. Notable features include a single valve cap for easy access to check valves without removing hoses, an outboard cylinder for convenient plunger packing inspection or replacement without hose removal, and main shaft seals with a dual wiper enclosed in a grease cavity to flush out contamination, extending the pump's lifespan. The NGP-7055-S is constructed with Viton piston packings and Buna O-rings and rod packings, making it suitable for use with liquid fertilizers that have a pH greater than 5 and standard herbicides compatible with these materials. Accessories such as the 116205-91 flow-thru style hydraulic motor/PWM manifold kit and the 116205-91D dead-head style hydraulic motor/PWM manifold kit are available to enhance the pump's functionality.
