Abstract
An improved sampling pump has utility for withdrawing fluid from a pressurized source and outputting fluid to a sampling container. The fluid pump assembly of the present invention includes an operator unit for reciprocating a plunger, and a side body port positioned within the pump body for receiving a removable filter. A pressure regulator has an inlet positioned within a side body port of the pump body and regulator outlet port in fluid communication with the operator unit. A collar rotatable with respect to a regulator housing is provided for reducing installation costs and for optionally removing condensate from the regulator. An adjustable discharge valve is pressure balanced for increasing the reliability of the pump. An improved seal is utilized for dynamic seal engagement between the pump body and the pump plunger.
