Pump Flows are in lb/hr & GPM Flowed Using Methanol: .795 specific gravity at 70°F Safety: To prevent pressure from reaching the shaft seal, pump pressure is not allowed to enter the lip seal chamber. Around the drive shaft is sealed to the housing and to the moveable plate by o-ring. This reduces the possibility of a seal leak and reduces friction on the drive shaft, because pressure is not forcing the seal lip to grip down onto the shaft… gives longer seal life and a reduction in required drive torque. The seal cavity is vented back to the inlet side of the pump to further insure that there is no pressure on the seal. A snap ring positively locates the seal. 3/8” hex drive coupler. Trim to proper length to provide .050” to .080” end clearance Inlet and outlet bolt-on fittings allow a larger diameter inlet port for better flow and keeps the housing strong because it isn’t tapped for a large fitting thread. 8AN Female 8AN 10AN 12AN 16AN Larger Inlet Mount Flange on 20AN.
