Description   Water pumps move water that does not contain suspended solids or particulates. These pumps are not so much a type of pump as they are a classification based on the media being transferred. Nearly every pump type that is defined by either a complementary application (fountain water pumps, submersible water pumps) or by motive type (such as centrifugal, cantilever, or hand water pumps) can be used in water service applications.

Q:
What new technologies are influencing water pump design?
16 answers
Answers:
Biologicals for agriculture use. Living fertilizers contain beneficial microorganisms and the pumps must not damage them, but we need enough flow/throw to apply the material to trees and crops in spray systems with 300 ft of 1/2" hose.

Q:
From your perspective, which companies are creating the most innovative water pumps?
15 answers
Answers:
Shurflow diaphragm pumps are pretty good. D/C is good but the psi is too low and flow could be better. Aquatec is better with psi of 70 but flow is only 5.2 gpm.

Applications and UseTop

Q:
What are some of the applications you have used water pumps for?
20 answers
Answers:
Sump pumps, waste water pump, pond pump up to 4200 gph. Pump for fountain. All of the the above are centrifugal pumps. Shurflo diaphragm pump. Allta electro magnetic diaphragm air pump .
~Jean Marc M, Retired, Saint Lazare, Canada
Delivery of fertilizers, and biologicals for agricultural uses. Specifically diaphragm pumps because they tend not to damage the biologicals during application.

FeaturesTop

Q:
What would your design or feature "wish list" be for this product?
10 answers
Answers:
Ideal pump would be a D/C diaphragm pump with 20 gal/min and 120 psi with a pressure switch that can be used continuously for skid sprayers.
~Caleb A, Manufacturer, Santa cruz, CA
A small pump with about 55 PSI to empty rain barrels up to 6. The pump should use bearings instead of bushings, 120V.
