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:
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.
Pressure ratings: 62 - 104 psi
Flow rate: 82 - 140 gpm
Speed: 600 or 1000 rpm
Series 1500 Gas Engine-Driven Centrifugal Pumps
As their name describes, this series can be mounted onto a gas engine. They are available with or without a mounting base for easy and secure installation depending on your engine. Need a pump that can tackle more than just spraying? Fill tanks, water seed beds and transfer liquids fast and efficiently with Hypro’s centrifugal pumps.
Pressure ratings: 65 - 140 psi
Flow rate: 98 - 150 gpm
Series 9300 Hydraulically-Driven Centrifugal Pumps
Hypro Hydraulically-driven pumps are capable of achieving high speeds while providing smooth performance. One of their advantages is that they can be easily mounted on a tractor or sprayer. Another great feature is Hypro's "close-coupled" design which saves space on your set-up by
Pressure ratings: 120 - 180 psi
Flow rate: 100 - 214 gpm
Hydraulic ports: 1/2" NPT inlet, 3/4" NPT tank
There are a lot of other options when it comes to spray pumps, each better-suited for a variety of applications. Stay tuned for future posts on how to service and troubleshoot your Hypro centrifugal pump, so don't forget to subscribe to our blog.
