The mts PERFORATOR 2-Component Injection Piston Pumps DP 40 PU-N pump is a robust constructed injection pump for high flow rates and pressures, which is generally used as a pipeline-pump. The pump can handle most materials on a polyurethane, silicate resin base with a mix ratio of 1:1


The Advantages of the DP40PU-N pump is that they are very easy and safe to use. They have a max. operating pressure of 2,973 psi (205 bar) with a max. flow rate of 25 l/min.


Applications for Resin Injection include:


  • Rock or concrete consolidation
  • Stop water ingress
  • Roof support
  • Gravel bonding
  • Cavity Filling 
General Information

Pneumatic Piston Injection pump DP 40 PU

The pressure injection pump Type DP 40 PU is a pneumatically driven, single acting piston pump that operates after the pressure intensification principle. The area ratio of drive pressure to pressure piston ring area yields the pressure ratio which is 41:1 in type DP 40 PU pumps. 

The pump consists of a pneumatically actuated drive part and a high-pressure part. Drive part and high-pressure part are linked with a piston rod. Two parallel high-pressure pistons are arranged at the end of the piston rod and are connected via a yoke. Thus, the drive and high-pressure parts are isolated and it is prevented that pump medium gets into the pneumatic drive part in case of leakages in the high-pressure sealing. The piston rods are of high-tensile stainless steel and boast long service lives. The valve seats are of tempered steel and the sealings of wear resistant UHMW-PE.
