High Water Pressure Pumps for Irrigation

Posted on Jul 20, 2020

Irrigation pumps for commercial use of sprinklers. High pressure irrigation pumps. There are other self-priming water pumps at high altitudes. High pressure water pumps ideal for irrigation of golf courses, lawn sprinkling, fire protection, swimming pools, industrial, marine and general applications where higher flow speeds and higher lifting heights are needed. Available in versions 3, 5, 7½, 10, 15 horsepower, single-phase (115 / 230v) and three-phase (230 / 460v) with heads up to 270 FT and flows up to 325 GPM.

Designed for industrial use with the choice of an electrical or flexible connector. Sprinkler / irrigation pumps are designed for various applications. For example, they can be used for drying barges and tanks, drainage mines or underground storage facilities. Homeowners use them for sprinkler installations and waterfalls. When it comes to moving water from one place to another, self-priming tasks can't do it!

Fast, positive priming: The pressure in the housing is balanced during pumping, which prevents loss of capacity due to recirculation. During operation, you get the maximum pumping capacity at the lowest cost.

The pumps can also be supplied in high-strength housings: The highest-quality cast-iron housing with a fine-grained construction has thick wall sections for more durable operation in adverse pumping conditions.

High pressure pumps

When the pressure is on, Honda high pressure pumps deliver! Ideal for applications such as sprinklers and nozzles, they are compact, easy to start and highly reliable. A commercial class pump with an overhead motor ensures quiet operation with excellent torque and exceptional fuel economy. Choose from different models to get the capacity and psi that your job requires.


These types of pumps can be used for pressure testing, cold cutting, paint removal from any steel structure, paint removal from ballast tank, paint removal from ship, paint removal from oil tank, cutting and demolition of concrete, removal of white and yellow road lines , pipe cleaning and many other applications in many industries.

High pressure piston pumps and high pressure piston pumps belong to the positive displacement pump family. These types of pumps can operate under continuous operating conditions, but require full discharge of the pump flow or bypassing part of the flow through the pressure relief valves. Typically, a portion of the bypass flow is recycled to the water supply tank or can be recycled back to the pump inlet side.

Piston and piston pumps have two or three piston or piston assemblies that generate pump flow and pressure. These pumps are usually powered by electric motors, hydraulic motors, gas or diesel engines. The drive speed determines the specific flow rate for a specific pump. Pumps should not be operated above rated speed or rated pressure. Belt drives or direct drives are available in many flow and pressure ranges.

Piston and piston pumps are ideal for use in car washes, truck washes, pressure washers, industrial cleaning, wastewater treatment, water washing, fogging, reverse osmosis and carpet cleaning.

Piston and piston pumps can vary flow rates from less than a gallon per minute for fogging applications up to hundreds of gallons per minute for sewer cleaning and industry. Pressure ranges can be from 200 PSI for low pressure cleaning to over 20,000 PSI for water sandblasting applications.

Piston and piston pumps usually have brass, chrome or stainless steel manifolds with Viton® seals for chemical compatibility. Most pumps have a liquid temperature of 140-160 ° F, but can be adapted to 180-200 ° F for special applications. Pumped fluids must usually be clean soapy water or chemicals added to the pumped flow before or after the pump.

You tried water. You tried soap. You tried to scrub and scrub. You've tried nasty chemicals that don't do what they say. So what do you do when it's not clean? Expand the pressure washer! Many people now routinely use these super-powerful hoses (also known as "electric washers") to clean objects with a water jet at a pressure about 100-200 times greater than the air pressure around us (that is, 1500-3000 pounds per square inch or psi). Perfect for terraces, driveways, garden furniture, barbecues and all kinds of other external dirt. Let's take a closer look at how they work!

Why do pressure nozzles clean things?

There is a good scientific reason why water makes things so clean: its particles have a small electric polarization (one end is positively charged and the other is negatively charged), so they tend to stick to everything themselves. Detergents (soaps) help the water do its job even better by breaking down sediment and fat and facilitating flushing. But some types of land on earth just don't move, no matter how hard you try. That's when the pressure washer comes in handy. Uses a narrow, high-pressure stream of hot or cold water to remove dirt. Because water flows quickly, it hits the dirt with high kinetic energy, throwing away dirt and dust like a continuous rain of small hammer blows. It's only water, though, so it doesn't damage most hard surfaces. Having said that, it's a good idea to test a pressure washer on an inconspicuous area before you start work to make sure it doesn't harm the surface you're cleaning. Always read the instructions before you use a pressure washer!

Parts of water under pressure

A pressure washer is less complicated than it seems. It's really just an electric motor driven water pump. The washer draws ordinary tap water (this is a tap for you in the UK), the pump accelerates the water to high pressure, and then squeezes it out of the hose at a high speed through the trigger gun. At the end of the hose you can mount various other tips for cleaning different things.

So here are the main parts that you will find in a pressure washer:

Water inlet: A hose connecting the pressure washer to the main water source. There is usually a filter on the inlet to prevent dirt and debris from entering the washer and clogging the work. Small pieces of sand are the last thing you want in the washing machine - especially since they can explode from the other end at high speed!

Electric motor or gas engine: Most smaller pressure washers (such as the very popular Kärcher ones) run from a domestic power source, but larger models are powered by compact gasoline engines. The engines are similar to those found in mowers (usually the rated power is around 3-4 kW or 3.5-5.5 HP). Models with gas engines are great if you work outside in places where it is difficult to find a source of electricity (or where a long pulling cable would be dangerous or uncomfortable). The engine is designed to supply a water pump.

Although household pressure washers are usually powered by electricity, larger ones are often powered by small gasoline engines and produce much stronger water jets.

Some engines inside a typical gas-powered washer used by the US Marine Corps being refilled ready for cleaning helicopters. They are rated at a pressure of 3400 psi (roughly 230 times normal atmospheric pressure), which is about three times more than an average home Kärcher. It's just about the most powerful washer you'll come across!

Water pump: this is the heart of a pressure washer. It's a bit like a manual ground water pump - it is only driven by a high speed electric motor (or gas engine) instead of a hand. When the engine pulls the pump to one side, it draws tap water; when he pushes the pump the other way, the water gushes with a high pressure jet. The pumps are designed to handle a water flow of about 1-2 gallons (4-8 liters) per minute.

High pressure hose: this is the pipe that runs from the washer to any cleaning device that you choose to use. A simple piece of tube would not be able to withstand the high pressure of the water flowing through it. The high pressure hose is reinforced with a wire mesh and has two or more layers of high density plastic. It is important to use a hose with a higher rated pressure than the pump in a pressure washer, but if the washer is delivered with its own hose, there should be no reason to worry. Typically, the safety margin for pressure washer hoses is around 300 percent, so if your washer is 2000 psi, the hose should be able to withstand a pressure of at least 6000 psi.

Cleaning attachment: depending on what you clean, you can switch from a simple trigger gun (basically only a valve that lets water only after squeezing the handle) to a spray with a rotating wand or a rotating brush to scrub the disk.
