KMT McCartney PMH Single & Dual Peroxide Injection Pumps
The KMT McCartney PMH hydraulic-driven reciprocating metering pump has long been the industry workhorse for initiator injection.
The KMT McCartney PMH Pump, now available with Single or Dual Intensifiers, is the latest generation of reciprocating peroxide injection LDPE pumps.
The PMH pump includes the newest proven designs for the intensifier top works as well as the hydraulic drive unit. These pumps are equipped with state of the art electronic controls, replacing the now obsolete pneumatic controls used for many years. This new electronic control system can be programmed to suit any specific process, providing precision control of initiator flow and reactor temperature.
Pump units are available in single configuration or in a dual configuration when space is a consideration. Single and dual pump units are supplied with manifolded process suction and discharge piping with single point connections. Check valve cooling jackets are an option when initiator flashing is a concern. High pressure cylinder cooling jackets are standard.
