Plant, components and devices for very high and high pressures (7000 bar and over) LIQUID PUMPS SERIES R AND R2

INTRODUCTION MCS® air-driven pumps operate on the simple but efficient principle of an automatic reciprocating differential area piston. A relatively large air-operated is connected to a smaller high-pressure piston to convert compressed air flow into fluid flow at high pressure. MCS® offers a complete range of single acting ratio pumps and double ratio pumps. The single acting pumps (R series) have one air piston and one high-pressure piston. The double ratio (R2 series) have two air piston and one high pressure piston. The diameter of the hydraulic piston varies and determines the ratio...

Check valve seats can be replaced within minutes. The check valves have soft seats, preventing capacity loss after a certain time of operating. Unlike other air driven pumps the air piston sealing and the pilot valve sealing of a MCS® airdriven pump is not an O-ring. It is provided with PTFE based slydrings (bearings) for excellent wear- and-slide qualities. The slydrings increase the service life of the sealing surface (air cylinder/air pilot valve) and the air piston sealing. Excellent control of flow and output pressure due to low frictional resistance of the air piston, even at low air...

As the frictional resistance of the MCS® air-driven piston is very low, only a small pressure drop or air drive pressure increase is required to restart the pump. The MCS® air-driven pumps can be mounted in any position. For maintenance reasons you are advised to mount pumps in vertical position, using the four thread holes in the air drive end caps or the mounting brackets. The pumps will deliver their rated capacity at 7 bar (101.5 psi) air drive pressure with the required air flow. The air supply line requires an air pressure regulator to control the output of the pump and a pneumatic...

NPT CONNECTION NPT threads must be sealed using a high quality PTFE tape and/or paste product. Refer to thread sealant manufacturer's instructions on how to apply thread sealant. - Sealing performance may vary based on many factors such as pressure, temperature, media, thread quality, thread material, proper thread engagement and proper use of thread sealant. - Customer should limit the number of times an NPT fitting is assembled and disassembled because thread deformation during assembly will result in deteriorating seal quality over time. When using only PTFE tape, consider using thread...
