Model B503 Plastic Air Operated Diaphragm Pump
Flow Rates to 900 LPM (238 GPM), Pressure to 70 Meters (99.7 PSI)
B503 plastic Air Operated Diaphragm Pumps are characterized by exceptional performance, power and strength, making them ideal for pumping liquids with very high apparent viscosity up to 50000 cps (at 20°C), even if containing suspended solids.
The stall-prevention pneumatic system assures a safe running pump and it does not require lubricated air. Self-priming dry capacity even with considerable suction head, fine tuning of speed without pressure loss and the possibility of dry operation without suffering damage mean that these pumps offer unrivalled versatility.
