The British Engines group of companies design manufacture and market a wide range of engineered products for offshore, electrical, construction, engineering and other industries, employing over1,000 people in North East England. Features • Designed specifically for the Polyurethane foam industry from over 20 years application experience and development. • Uniform fluid temperatures throughout the pump. • Designed for high inlet pressure. Twin PTFE seals running on a ceramic bush allow up to 20 bar. •...

MAXIMUM PUMP SPEED (RPM) FOR FLUID VISCOSITY Technical data Technical data GUIDE TO PUMP SELECTION Notes for technical data table 1. Maximum allowable speed reduces for high viscosity fluids. Refer to Graph 1. 2. Minimum speed is determined by flow stability. 3. Pressures shown are for fluids complying with cleanliness codes stated in this table. 4. Outlet pressure must never fall below inlet pressure this includes during stationary and start up conditions. 5. Inlet pressure should be kept to the minimum value possible, based on the characteristics of the fluid and other factors - see...

Operating pressures - general The pump design features hydrostatic bearing faces for optimum efficiency and long life. The hydrostatic balance required for these bearings means that inlet pressure must never exceed outlet pressure, even when the pump is not rotating. This is normally simple to achieve on tank pressured systems. For systems using boost pump this may be possible by using a relief valve or by placing a check valve in parallel with the pump. This is to allow a possible flow from inlet to outlet so that pressures can be balanced from inlet to outlet during start up of the pump...

Commissioning & installation Accessories & ordering code Magnetic drive couplings Relief valves Pump shaft rotation must be in compliance with the pump body indicators i.e. CW means clockwise shaft rotation whilst looking from the shaft end of the pump. Recommended inlet pressure should always be maintained at the inlet port at start up and during running. Pumps fitted with manual variable displacement controls should not be adjusted when the pressure, at either port, is greater than 100 bar. Magnetic drives can be installed to give high reliability with zero leakage. May require cooling...
