Mini-mum recommended differential pressure is 40 PSI (2.8 BAR).Inlet Pressure 200 PSIG (13.8 BAR) maximum.Viscosity 45 to 3000 SSU (6 to 650 CST).Temperature 0 to 250°F (-18 to 121°C).Drive Direct only.Rotation Clockwise facing pump shaft.Mounting May be foot mounted in any orientation.Filtration Inlet strainers are required to keep contaminants and abrasives out of the pump. Theymust be selected in consultation with the strainer vendor to prevent pump starvation.Normally, 25 micron or finer is recommended.Maximum Speed* 4400 RPM maximum for sizes 118 thru 156. 3600 RPM maximum for sizes 187 and 200.* Assumes minimum inlet pressure requirements are met.10-100 GPM (38-378 L/M) Pressure to 4500 PSIG (310 BAR)12L series pumps are designed for high pressure applications such as compressor gas sealing,hydrostatic bearings and fluid power services. Operating noise levels are typically below 75 dBA atfull pressure and two pole motor speeds. The cast steel case and balanced shaft seal with carbon oncarbide faces are intended to offer compliance with API requirements. Pump inlet port is rotatable in90 degree increments to suit piping layouts. The pump includes mating carbon steel SAE 4-bolt,6000 PSI rated socket weld flanges. Pump casing is hydrostatic tested to 7500 PSIG. 12L seriespumps have become the world standard for gas sealing services on high pressure centrifugal com-pressors in process, refinery and offshore applications.SIZE A B H L W WEIGHTINCH MM INCH MM INCH MM INCH MM INCH MM LBS.
