PVA’s SPP Servo Piston Pump system is the ideal choice for precise metered dispensing of heavily filled and abrasive materials. The SPP’s piston displacement design is equipped with a tungsten carbide sleeve that provides a zero dead space shot meter and long service life under adverse conditions.
An inert barrier fluid provides no contact with the atmosphere, keeping seals lubricated and free from material crystallization. The SPP system is perfect for moisture sensitive fluids like isocyanate urethanes.
Via a menu-driven HMI, the closed loop servo drives enable the programming of several functions including shot size, mix ratio, flow rate, pressure control, recirculation, and auto purge.
