This manual explains the installation and operation of the PM-80 Pump, as well as procedures for routine maintenance and troubleshooting. Read the entire manual prior to installation and start-up.

The PM-80 is a reciprocating, dual-piston unit. It is designed for precise and reliable solvent delivery for isocratic and (optional) gradient elution at flow rates between 0.01 and 5.0 mL/min. Advanced features of the PM-80 pump include:

• Type 316 stainless steel tubing throughout.

• A microprocessor-controlled, computer-designed, dual-piston pump. Each head is removable as a single, precision-engineered assembly, which may be interchanged in seconds. The construction of the pump is solid (cast aluminum and machined 316 stainless steel); no sheet metal is included. The end result is greater durability, mechanical reliability, and serviceability.

• Solid-state pressure transducer, to monitor system backpressure in real time.

• Pulse damper, installed as a standard feature for use at high sensitivity.

• Purge valve, for bypassing the column and injector while flushing the solvent delivery system.

• High- and low-pressure limit controls, for safety.

• Analog output for pressure monitoring.

• Provision for remote-control operation.

• Optional ternary gradient capability. Contact BAS for information on upgrading your isocratic PM-80 to a gradient system.

The PM-80 has been engineered for durability, and with proper maintenance should provide years of reliable service.
