Screw pumps for 1-phase machines
Maintenance-freee versions or versions that require clamping
Also as far as screw pumps for 1-phase machines are concerned, Maltech Srl offers a variety of maintenance-free and clamped / clampable products. Further adjustment is not required due to the strong tightness between rotor and stator. The indicated conveying capacity is an approximate value that may vary according to type and consistency of the material in use.
