Northern Hydraulics stocks pressure washers for industrial, fleet, and shop cleaning – gas and electric drives in both cold-water and hot-water configurations, rated by working pressure (PSI) and flow (GPM). The right unit is the one whose pressure and flow match your cleaning task, water supply, and power source, with a pump and unloader built for the duty cycle you run. Running an older or discontinued machine? send your specs for a cross-reference.

How to Choose a Pressure Washer

Working pressure (PSI) — the force delivered at the nozzle; light surface cleaning runs lower PSI while caked grease, paint prep, and concrete typically need higher PSI. Match pressure to the toughest surface you clean, not the average job.
Flow rate (GPM) — gallons per minute drives rinse speed and how fast you clear loosened debris. Higher GPM cuts cycle time on large surfaces; confirm your water supply can keep up with the unit's rated demand.
Power source — gas engines run cord-free for remote and outdoor work; electric motors suit indoor or enclosed areas where exhaust is a concern. Verify available voltage and amperage before choosing an electric unit.
Water temperature — cold-water units handle general dirt, mud, and debris; hot-water units cut grease, oil, and food residue faster and typically reduce detergent use. Confirm the burner fuel type on hot-water models.
Pump and unloader — the pump sets duty cycle and service life, and the unloader protects it when the trigger is released. Match the PSI and GPM ratings of the pump to the engine or motor driving it.
Duty cycle — how long the machine runs per shift; occasional cleanup tolerates a lighter unit, while continuous washdown needs a heavier pump and frame built to run for hours without overheating.

Which Pressure Washer Is Right for the Job?

Pressure washers split along two lines: power source and water temperature. Pick a gas, cold-water unit for outdoor fleet washdown, equipment, and agricultural cleanup where you need portability and high flow. Choose an electric, cold-water unit for indoor bays and enclosed shops where engine exhaust is unacceptable. Step up to a hot-water unit when grease, oil film, or baked-on residue resists cold water — heat does work that pressure alone cannot. To confirm fit, list the surfaces you clean, the worst soil you face, your water-supply GPM, and your available power, then check that the unit's PSI, GPM, and burner spec meet all four. If you are matching a machine already in service, send the model and pump number and we will confirm the equivalent.

Complete the System

A pressure washer is one part of a working cleaning setup. Pair the unit with rated Hydraulic Hoses and high-pressure lines suited to its PSI, and use Pneumatic Quick Couplers for fast hose hookup and accessory swaps. For mobile rigs and equipment driven off auxiliary power, we also stock Hydraulic Pumps, Hydraulic Motors, and Hydraulic Cylinders to keep the carrier machine running while you clean. Sourcing these together off one order keeps your lead times aligned and your hookup ratings matched.

Cross-Referencing an Obsolete Pressure Washer

When a pressure washer or its pump is discontinued, the value is in the equivalent — a current unit or pump that matches the original PSI, GPM, drive, and mounting so you can keep cleaning without re-plumbing the whole rig. Northern Hydraulics has cross-referenced hydraulic and cleaning equipment since 1963, and we can often match a retired machine, pump, or unloader to an in-stock replacement. Send the model number, pump number, and pressure and flow ratings, or a photo of the data plate, and request a cross-reference.

Pressure Washers – Frequently Asked Questions

How do I size a pressure washer for my cleaning job?

Match the unit to the toughest surface you clean. List the worst soil (mud, grease, paint), the surface area, your water-supply GPM, and your available power, then choose a unit whose PSI and GPM meet all four. Sizing for the hardest task avoids buying a machine that stalls on grease or runs out of flow on large jobs.

What PSI and GPM do I need?

PSI is cleaning force and GPM is rinse speed; you need both. Light vehicle and surface cleaning runs lower PSI, while concrete, paint prep, and caked grease typically need higher PSI, and larger areas benefit from higher GPM to cut cycle time. Confirm your water source can supply the unit's rated GPM before you buy.

What's the difference between a cold-water and a hot-water pressure washer?

Cold-water units rely on pressure and flow alone and handle general dirt, mud, and debris. Hot-water units add a burner that heats the water, cutting grease, oil, and food residue faster and typically reducing detergent use. Choose hot water when oily or baked-on soil resists cold cleaning, and pair either unit with the right Pneumatic Quick Couplers for fast hose and accessory hookup.

Should I choose a gas or electric pressure washer?

Gas engines run cord-free, which suits outdoor, remote, and fleet washdown where you need portability and higher flow. Electric motors suit indoor bays and enclosed shops where engine exhaust is a concern; verify available voltage and amperage first. The cleaning task decides the rest — power source does not change the PSI and GPM you need.

What hoses and fittings should I run with a pressure washer?

Use high-pressure hose rated at or above the unit's PSI, and quick couplers sized to the machine. Browse rated Hydraulic Hoses and Pneumatic Quick Couplers to complete the hookup. Matching the hose rating to the pump protects both the operator and the equipment.

Can I run a pressure washer off my equipment's hydraulics?

Hydraulic-driven cleaning setups run a pump off the carrier machine's auxiliary circuit. If you are building or maintaining one, we stock Hydraulic Pumps and Hydraulic Motors to match flow and pressure to your circuit. Send your system pressure and GPM and we will confirm the right components.

How do I find a replacement for a discontinued pressure washer or pump?

Cross-reference by matching the original PSI, GPM, drive, and mounting to a current unit or pump. Send the model number, pump number, pressure and flow ratings, or a photo of the data plate, and we will identify an in-stock equivalent. request a quote.

Do pressure washers ship the same day?

In-stock pressure washers ship same day from Great Falls, MT when ordered before the daily cutoff. Stock and lead time vary by model and configuration, so confirm availability on the product page or ask a parts specialist before you order.
