Udor Zeta-PP 42

The Udor Zeta-PP 42 VAGR3/4 is a low-pressure 3-cylinder diaphragm pump featuring an anodized aluminum body, polypropylene heads and manifolds, and stainless steel valves. All models come with a standard control valve and pressure gauge. This model is designed with gear reduction for a 3/4″ shaft gas engine (4-6.5 HP) and weighs 31.3 lbs.

• GPM: 10.5
• PSI: 300
• RPM: 550
• Inlet Port: 1-1/4″ Hose Barb
• Outlet Ports – Valve: (2) 1/2″ Hose Barb
• Bypass: 3/4″ Hose Barb
• Greentech Diaphragms
  • Redesigned shape guarantees less cavitation & deformation
  • Greater mechanical strength and flexibility
  • More resistant to temperature variations
  • Chem compatible

• Greentech diaphragm formulation engineered for broader chemical compatibility and better temperature stability versus legacy blends. That directly translates to longer life when circulating SH and surfactants.

• Polypropylene wet-end(heads/manifolds) + stainless-steel valves/liquid parts these materials are far more corrosion-resistant to hypochlorite than bare aluminum heads, reducing pitting, swelling, and premature seal failure.

• Softwash-optimized design ZETA-PP softwash variants pair the chemical-resistant wet end with low-pressure, high-flow diaphragm geometry so you get smooth delivery without surface damage, ideal for SH application and rinsing.
