The 3-diaphragms pump ZETA-PP 70 produces a flow of 71 l/min and operates at a maximum pressure of 20 bar. It is available with single or double splined/cylindrical shaft.
Semi-Hydraulic diaphragm pump features heads, pipes, and manifolds made of reinforced polypropylene, compatible with plant protection products. The crankcase is made of die-cast aluminum with cataphoresis coating for corrosion resistance. The valves are designed with a spherical profile to increase volumetric efficiency.
Metal plates reinforce the head, and additional metal tie rods provide extra support for the pipes and pressure regulator. Valves cages in Kynar ensure maximum chemical resistance. The valve plate, seat, and valve spring are made of SS316 stainless steel. O-rings are in VITON. A reinforced polypropylene regulator is included and comes pre-assembled on the pump.
The pump comes standard with the new GREENTECH diaphragm, made of an innovative material that reduces deformation from use and improves both mechanical and chemical resistance.
The pump is also available in the MI version (hollow shaft), which allows for direct coupling of the hydraulic motor to the power take-off.
