High Pressure Pumps for Sale – What You Should Know

High pressure pumps are used to pressurise water, other liquids or gases. These pumps form the core parts of many high pressure washers and cleaners, since the water-detergent combination they eject at high pressures are capable of loosening the adhesive bonds between contaminants and the surfaces or substrates they are bound to. High pressure pumps offered for sale come in many different shapes, sizes and builds, but armed with a bit of knowledge, you’ll be able to make the right choice…

Aside from the various technical differences, there are two types of pumps: high temperature pumps, and normal to low temperature pumps. High temperature models are typically used in applications where the heat of the liquid being pumped combined with a detergent serve to remove contaminants that change chemically or physically when brought into contact with the combination. Instances where one may be used include the cleaning of oil rigs, restaurants, conveyor belts, vehicles and other instances where sanitation is important, or where grease and grime are the main contaminants. Pumps capable of handling normal to low temperatures are typically used for cleaning purposes where heat is not a requirement, on construction sites for example, or to pump other, more solid substances like slurry.

These two types can then be further subdivided into belt drive pumps, and their direct drive counterparts. Belt-drive models are typically used in industrial settings, and may be a distance removed from the engine. Direct drive models are more commonly used in commercial applications since they are attached to the driving engine. Commercial pressure washers and even car wash installations rely on direct drive models.

The choice between hot and cold as well as belt drive and direct drive pumps should be based on the application of the pump (in other words, where it will be used) and the installation of the pump (whether it will be installed on a portable unit, like a pressure washer, or in a fixed industrial setting).

Following that, it’s down to the technical specifications. Two of the most common factors these devices are chosen on include the flow rate (measured in gallons per minute, or GPM, or litres per minute, or L/M), and pressure (measured in pounds per square inch, or PSI, or bar). The flow rate isn’t directly proportional to the pressure, and should be chosen based on the final assembly. The flow rate is also not an indication of how much liquid will be consumed each and every minute – it’s simply a maximum capability. Pressure should be based on the application of the unit. In most instances pumps with a higher maximum pressure than needed for its application are chosen. Depending on the installation of the unit, pressure and flow rate may be controlled and varied according to need (requires a separate mechanism).

Combine the drive requirement with the temperature, pressure and low rate, and you’ll be able to choose the right one among a range of high pressure pumps for sale. And since they are built to last, it’s an investment in productivity, and therefore the entire business.
