Micropac MC Miniature Hydraulic Hand Pump

The Micropac MC is a truly miniature hydraulic hand pump with a 20cc integral reservoir, a release valve and relief valve. Not all hydraulic systems are large volume. If you have a very small actuator, pilot to pressurise, braking system or are simply calibrating and testing, the MC unit offers a flexible, high quality manual power solution with an amazingly small space envelope. Use one MC miniature and cost-effective pump close to the actuator and eliminate bulky hoses or pipework. Design a testing or calibration rig that takes up the same bench space as an office stapler. Designers use it where they can see the opportunity to fit a compact hydraulic cylinder in place of a laborious screw jack. The unit was developed for a hydraulic crew seat in conjunction with an innovative Micropac pull cylinder and connected with a small bore Polyflex hose. Lots of applications since have benefitted from this Micropac miniature hydraulic hand pump. We have integrated three and four-way port valves for applications including actuation, control systems and ground support equipment. A stainless-steel version with a 316-stainless body, piston rod and ancillary parts provides corrosion resistance in harsh environments. The 20cc reservoir is cleverly integrated into the body and if you can design your system around this, you will achieve a truly miniature 400 bar hydraulic system for use on mineral oil. If you require a larger volume, we offer a 175cc reservoir.

Description

The MC series is a miniature 0.6cc per stroke, single acting hand pump. The hard-chromed piston rod runs in a bronze bearing for long life. The ultra-compact pump body is fitted with inlet and outlet non-return valves, a relief valve and a release valve. These two valves can be blanked with Micropac cavity blanking plugs for flexibility to suit your exact application. There is a 20cc reservoir integrated into the pump body with a G1/2 filler/breather and strainer mesh. If you need a larger reservoir, a 175cc tubular reservoir can be fitted. The pump is mounted using two M8 tapped holes in the body or using an angle bracket that we can supply. There is no provision for through holes in this compact pump body. The base model is carbon steel but a unit with a 316 stainless body and other parts is available. The outlet port is 1/8npt female, however we do offer adaptors if required. Contact us to discuss the best possible arrangement for your Micropac MC miniature hand pump. The unit should be piped up using tube (typically 6 or 6.35mm o/d) or a small-bore hose, typically -2 or -3 sizes.
