Servicing a Micropac Hydraulic Hand Pump: The Complete Guide

Ever wondered how you can service and breath a new lease of life into your hydraulic hand pump? In this video we'll show you a step-by-step walkthrough on how to disassemble and service repair your pump. Whether to fix leaking and worn out seals, or to change the compound for new applications, our service kits can help you to extend the functionality and life-span of your pump, and doing it yourself will save on potential downtime and lost profits.

On day one, our company ethos was to make our equipment serviceable and maintainable, not throw-away. 35 years ago, people reused and repaired, and the throwaway society hadn’t yet happened. We engineered our hydraulic pumps as we expected professional equipment to be, offering low cost service kits and easy maintenance.
We stand by our kit that can be repaired in the field, and still get pumps back into our workshop for repair from 1983. Selling comprehensive service kits and spares at modest prices means repairing your kit is a viable and affordable option, instead of opting for new.
