MasoSine`s EcoSine pump satisfies demanding processing requirements cost-effectively, using the unique  MasoSine pumping principle. This model is a sanitary pump for pressures to 6bar (90 psi)and bi-directional operation. The sine-wave-shaped rotor creates four moving chambers which gently convey the duty fluid from the inlet port to the higher-pressure discharge port. The gate prevents any fluid passing back from the discharge side to the lower-pressure suction side of the pump
