Product Highlight: Delavan Electric Diaphragm Pumps

Posted by Sprayer Depot on Mon, May 02, 2016

Electric diaphragm pumps, like ShurFlo and Delavan, are widely used in a variety of spraying applications. They are inexpensive, offer low-cost maintenance, and can effectively perform many jobs with ease. They are commonly used in spot sprayers, small skid sprayers and other spray equipment where spraying long distances is not needed. Due to their pressure rating limitations, electric pumps are not the best choice for spraying tall trees, roofs or high elevation areas. Customers looking to reach great heights will be better served by using a gas engine driven pump.

Electric pumps are great for greenhouse spraying to reduce fumes, or for quiet applications where noise levels could pose a problem such as spraying early morning around neighborhoods or through quiet zones.

Product Highlight: Hypro Centrifugal Pumps

Posted by Sprayer Depot on Mon, Apr 11, 2016


Centrifugal pumps are high flow, low-pressure pumps that can deliver pressure ratings of anywhere from 0 to 150 psi and flow rates up to 440 gpm. How exactly do centrifugal pumps work? Well, if you are feeling a bit technical, here’s a simple explanation: On a centrifugal pump, the liquid enters through the middle into an impeller that forces the liquid into the outlet of the pump.

Centrifugal pumps are known to be heavy-duty and durable due to their fewer parts and minimum wear surfaces. Another great feature is they are easy to clean and maintain.

They can be used in a variety of applications including agricultural and industrial spraying. They come in different materials such as cast iron, stainless steel, and even polypropylene, making them capable of handling a variety of liquids and chemicals. They are mostly used with water, insecticides, herbicides, wettable powders, emulsives, and liquid fertilizers just to name a few. Some centrifugal pumps, specifically those made from polypropylene, can handle acids and other corrosive liquids.

Centrifugal pumps can be powered by different methods, the most common include

Tractor/PTO

Series 9000 - 9400 Belt-Driven Centrifugal Pumps

This series is specifically designed for easy use with tractor mounted sprayers. They can handle big, high-capacity spraying jobs with ease and are easy to install/uninstall.

Product Highlight: Hypro Roller Pumps

Posted by Sprayer Depot on Wed, Jan 20, 2016

Hypro roller pumps are designed for creating and boosting pressure in fluid circuits. The economical rotary-action roller principle requires no check valves, while providing positive displacement characteristics with less friction and lower starting torque than other pumps.

Ever wondered how these pumps work? Basically the pump receives fluid through the inlet port where it's captured and transported by the rollers. Afterwards the fluid is expelled through the outlet port. Easy, right?
