cummins engine water pump , Iran

The Cummins engine water pump is of the centrifugal type with a closed impeller and a volute housing. The pump housing material is grey cast iron GCI-250 with an electrostatic anti-corrosion coating. The impeller diameter in the 6BT model equals 95 millimeters with 6 forward-curved blades. The KTA19 model features a 140 millimeter impeller with 8 blades and a thickness of 12 millimeters. The water pump bearing is a double-ball type with a diameter of 35 millimeters and a double lip seal. The axial clearance between the impeller and the pump housing in the original sample is set between 0.5 and 0.8 millimeters. The water displacement volume in the 6BT model is approximately 180 liters per minute at 2500 RPM. The QSK50 model has a flow rate of 650 liters per minute and an impeller diameter of 220 millimeters. The pump pulley is manufactured from ductile cast iron with 6 V-shaped grooves and an outer diameter of 130 millimeters.

The Cummins water pump supplies an output pressure of 0.8 to 1.5 bar at rated engine speed. The flow rate in the 6BT model equals 2200 liters per hour and in the KTA19 model equals 5500 liters per hour. The mechanical seal of the water pump is manufactured from silicon carbide with a hardness of 1500 Vickers. This seal is capable of withstanding temperatures of 130 degrees Celsius and pressures of 2.0 bar. The flatness tolerance of the stationary seal face is ground below 0.1 micrometers Ra. The minimum allowable flow rate at idle speed for the 6BT is 600 liters per hour. A flow drop below 400 liters per hour causes localized boiling and engine overheating. The service life of an original Cummins water pump is estimated at approximately 12,000 hours or 800,000 kilometers. The pump-to-block mounting gasket is manufactured from fiber material with a thickness of 1.2 millimeters and an inner diameter of 38 millimeters. The torque for the pump mounting bolts to the block in the 6BT model equals 25 Newton meters.You can order and buy cummins engine water pump from Iran by contacting us through whatsaap and email.
