Product Description:
The GX 45 PU is a pneumatically driven, single-acting piston pump that operates according to the pressure intensification principle. It features a pressure ratio of 45:1, achieved through the area ratio of drive pressure to pressure piston ring area. The pump consists of a pneumatically actuated drive part and a high-pressure part connected by a plunger. This design isolates the drive and high-pressure parts, preventing pump medium from entering the pneumatic drive part in case of high-pressure sealing leakages. The plunger is made of high-tensile stainless steel, ensuring long service life, while valve seats are made of tempered steel and gaskets of wear-resistant PTFE.

Application:
The GX 45 PU is a compact injection pump with small dimensions and low weight, yet it offers a high flow rate. It is primarily used as a pipeline pump to supply injection fluids based on Polyurethane in a 1:1 mixing ratio from gate road to longwall face.

Catalog excerpts

The pressure injection pump GX 45 PU is a pneumatically driven, single acting piston pump, operating acc. to the pressure intensification principle. The area ratio of drive pressure to pressure piston ring area shows the pressure ratio which is 45:1 for GX 45 PU pumps. The pump consists of a pneumatically actuated drive part and a high pressure part, which are connected by a plunger. Two parallel fitted high-pressure pistons at the end of the plunger are connected via yoke. Thus, the drive and high pressure parts are isolated, which prevents that pump medium could get into the pneumatic drive part in case of leakages of the high-pressure sealing. The plunger is made of high-tensile stainless steel and is distinguished by long service life.jjbe valve seats are of tempered steel and the gaskets are of wear-resistant PTFE. Application: The GX 45 PU is a compact injection pump with small dimensions and low weight, but with a high flow rate. It is mainly used as pipeline pump to supply injection fluids on Polyurethane basis and in a mixing ratio of 1:1 from gate road to longwall face. Within the specified technical features and performance data, engineering and design of our products are subject to change. To all products and services our general terms and conditions, incl. Product liability, apply exclusively. (Perforator, Technical Data Sheet PERFORATOR GmbH eMail: infodperforator.de • Internet: www.perforator.de
