Answers:
As an end user, do not skimp on quality. The biggest mistake I have seen in over thirty years of being involved in the industry is seeing users look at short term price (opting for cheap inefficient pumps and other system components) instead of long term gain. This happens over and over again with many hydraulic design engineers and component distributors perpetuating this problem by promoting the cheaper alternatives to "get the contract" vs designing a system that will last. This is a vicious circle that has been going on for decades. It wastes power and eventually cost the end user more money in the long term due to higher energy costs and higher replacement component costs. I have seen a slight change away from this with the current energy savings push but we still need to re-educate industry.

Ensure that when installed the system and pipework allow for the recommended maintenance envelope, that there are sufficient isolating valves and self sealing coupling to allow for flushing and filtering of the system without having to "break" the pipework.

In new start ups, make sure the piping in the system is clean. More equipment is damaged at start up by dirt in hose and piping than any system or equipment abuse.

Ensure you are well aware of the limitations and that you will lose HP when using hydraulic drive systems compared to standard drive pumps.

1- please know how big your system is before you decide to choose the pump to buy. ie max. flow demand needed for your system to operate.
