Buy from an expert. Someone who knows not only the product, the company that manufactures or markets it, but someone who can size the pump to suit your application's requirements. When I sell you a pump, I don't want to see you again, unless you have a new application that requires a pump.
~Kevin A, Service Manager and Sales, Ashfield, Australia
Every pump job design is different, so working with the pump manufacturer technical sales will ensure the lowest life cycle costs of a pump. The biggest mistake is installing a pump that is not designed for the system curve.
~Chad N, Technical Sales, Timmins Ontario, Canada
Please provide correct data when shopping for a pump, also please be expected to wait a lead time of at least 8 weeks before a pump is shipped. Special projects take even longer.... be prepared to wait!
~Aaron S., Marketing/Sales, Santa Ana, CA
Know the specifics of your application. What are you pumping (viscosity, specific gravity, soilds)? What is the expected pressure or head you need. Know the suction issues for your pump.
~Randal, Technical Support, Odessa, TX
Make sure you fully understand the capabilities of pump being selected with regards to suction pressure, flow, discharge pressure, horsepower requirements and type of shaft seals.
~John S, Sales Engineer, Quincy, IL
Allow extra time to sift through the disparate ways each company presents information. Make friends with a stocking distributor's technical sales rep.
~Chris F, Research & Development, Raleigh, NC
Pay big attention at brand of bearings, max working temperature of seal and material of pump shaft. Good choice will save maintenance costs in future.
~Hoang Xuan Niem, Managing Director, Ho Chi Minh City, Viet nam
Always Buy High Quality. The highest quality that your budget will allow. Purchase from pump people and not the catalog houses.
~Franklin H, Project Manager, Indianapolis, IN

~John L, Sales Coordinator, Toronto, Canada
There are many companies that produce pumps, be sure to select one with strong customer service and local representation.
~Troy Z, Marketing/Sales, Denver, CO
Impeller size of each pump selection to be selected just above the minimum. and motor size may be just at maximum, so as to modify later on both sides. I recommend min because we will not go to under size the pump. But we can up efficiency of the pump by taking tappings from the same discharge only by increasing the impeller size and if needs size of motor.
~Guha Prasad Swaminathan, Maintenance Manager, Lopburi, Thailand
1. In my country people are unable to by the c.pump because of the economy, but i would like to advise people to come together and buy the pump.
2. i would like to advise experts to alert people about the importance of irrigation so that they can seek the pump
3. i would like to advise people to take training about the pump.
