Q:
What would your design or feature "wish list" be for this product?
35 answers
Answers:
The best wish would be for industry standards becoming more uniform. It would be nice to pick up the phone and find a replacement pump off the rack in times of breakdown. Nobody likes to invest money in spares.
~Scott H, Project Manager, Kelso, WA
Smaller design envelope, faster speeds, new lighter build materials, built to operate with more Eco friendly materials, (although good now) improvement in electronic control integration.
~Rod R, Design Engineer, Victoria, Canada, B. C.

Optimum design feature of friction loss, bend loss, reliability, warranty criteria should be specified along with type of application of load.
~Sarvjot singh Singh, Production Engineer, Una, India
I wish they design a piston pump small. so you have a choice between a gear pump and a piston pump on a small application.
~Anthony R, Maintenence manager, Bogor, Indonesia
To reduce the physical size of components (without sacrificing quality or performance) and make hookups/disconnects easier.

Q:
Is there any advice you want to share with users to help them avoid common errors in selection or usage of a hydraulic pump?
20 answers
Answers:
Again, don't go cheap; I have seen hundreds of applications where the use of cheap pumps and other components mean using as much as 30% or more connected horsepower. Make sure you are full aware of not only the normal power consumption in your system but also intermittent demands. Make sure you have the proper control in variable speed and pressure systems. I have seen systems with expensive controls on the pump that will never be used and I have seen the opposite end as well, where flow and pressure control valves are used with fixed displacement pumps.
~Rod R, Design Engineer, Victoria, Canada, B. C.
Do not under size the suction or inlet line to the pump. If anything, up size this line to the pump larger then the inlet port size. Never downsize. Even with a pressure comp or pressure limited pump still install a system relief valve.
~Lyle S, Marketing/Sales, Houston, TX
Make sure the power unit will be large enough not just for the pump but for accessories you may purchase in the future. The possibilities are endless as far as accessories.
~Builder/Contractor, Newport, KY
Don't try to save a dollar by guessing or taking a chance that something will work. "Playing" with hydraulics is an expensive hobby and can lead to serious injury - "good stuff ain't cheap and cheap stuff ain't good".
~Steve M., Retired high school shop teacher/electrician, Snow Hill, NC
Must keep a clean system before you start running a new pump, tanks, valve blocks, hoses and tubes, everything in the loop of the system.
~Jim Y, General Management, Shanghai, China
Go for bigger than you need. Pumps running at or near capacity will disappoint due to over heating.
~Anthony S, Technical Support, Middleburg Heights, OH
Go with more out put that you really need so you have room for improvement in the future.
~Jonathan P, Millwright, Grimshaw, Canada
KNOW WHAT PRESSURE AND FLOW IS NEEDED AND DON'T GET A BIGGER PUMP THAN IS NEEDED.
~JERRY S, OWNER OF A REPAIR SHOP FOR AG EQUIPMENT, COLUMBUS, WI
Flow rate, power connection, fitting connection, and most horse power
~Joel Carrosino, OSM Supervisor, Dammam, KSA
For pumps on Aviation Fuel Service, water should not be cooling media.
~Hari C, Engineering Consultant, Mumbai, India
1- Always seek proper technical advice before buying or using a pump.
~Anthony R, Maintenence manager, Bogor, Indonesia
Ask someone that has used the same style you are planning on using.
~James E, Tinker, Lake station, IN
The lowest price is usually the pump you will visit again.
~Scott H, Project Manager, Kelso, WA
What input RPM for some of the versions of gear pumps.
~Technical Support, Savage, MN
Never operate a hydraulic pump with out medium.
~Vara Prasad, Engineer, Kakinada, India
Beware of rotation, duty cycle of application.
~Bill D, CFPS, North Bay, Canada
MAKE SURE YOU HAVE ADEQUATE HORSEPOWER.
~ED RYAN, Design Engineer, ORANGE, CA
