Corrosion is a very serious issue. External environmental corrosion may mean that the first time a pump is used after a long period of inactivity, it has seized up or fails. Internal corrosion from stagnant or aggressive fluid may cause failure or spread contamination throughout a hydraulic system.

Micropac hydraulic hand pumps offer solutions on a number of levels of corrosion resistance.

Our inexpensive but quality MW-A hand pump still uses a hard-chromed 316 stainless steel piston rod and stainless steel pivot pins. This is a lightweight hand pump unit with good corrosion resistance.

Our highly regarded MW-3 hand pumps use 316 stainless steel and bronze and can be upgraded to offshore trim for enhanced external corrosion.

Our large displacement MB Drum pump uses all 316 stainless steel and polymer wetted parts, as does our MU hand pump for unparalleled corrosion resistance.

Our MT-6 Cartridge hand pumps are 316 stainless steel variants for very compact and cost effective corrosion resistant manual hydraulic units.

For high external corrosion resistance and an “industry standard” footprint, our MG series uses our proven 316 stainless/1.4404 hand pump on a 316 stainless reservoir. Some of these units will retrofit in place of other manufacturers’ alloy and carbon steel units. An additional reservoir return or equaliser port simplifies installation. This equipment is used on sub-sea applications such as ESD systems and diving bell doors where alloy or carbon steel are unsuitable for safety and dependability.
