Gasoline Water Pump GWP20H2, Ideal for Pressure at Maximum Lift

Oil alarm system is equipped on this machine: when the oil level is too low, the gasoline engine will automatically stop running to avoid specific damage to the engine.
Aluminum alloy and durable cast iron body can withstand high pressure, more durable, simple and reliable structure, and maximized flow.
Using wear-resistant graphite, ceramic magnetic mechanical seal to provide excellent sealing performance.
The high-pressure pump adopts wear-resistant cast iron vortex shell and aluminum alloy impeller to maximize the rate of flow.


This high pressure water pump is powered by a 7.0 hp 4-stroke gasoline engine. It is designed for demanding jobs that require high pressures, or when you want to transport water to great heights; such as in sprinkler irrigation or firefighting.

The GWP20H2 gasoline water pump is built with a double cast iron impeller and a durable aluminum housing. It has 2” inlet connections and 3 outlets with triple connector, and a 2” thread, plus 2 1-1/2” threads.

It has a perimeter chassis that protects it from blows and its tank has great capacity.

Q       Do the gasoline water pumps need to be maintained?
A       All water pumps need regular maintenance, such as oil changes, to maintain peak performance over many years of dependable use. For routine maintenance procedures and schedules, consult the owner’s manual.
Q       What are the most common types of gasoline water pump?
A       Water pumps come in two basic categories. Positive displacement and centrifugal pumps
Q       Which Craftop gasoline water pump is best for your needs?
A       The easiest strategy to choose the best water pump for you is to be aware of your water usage needs. Look for characteristics like: Portable electronic ignition, flow, pressure, and suction While you should make sure you can transfer the necessary amount of water at the required rate, you shouldn’t get anything that will exceed your capacity requirements. If you’re unsure, contact our experts, and they can help you select a pump that will meet your water needs. To choose which model is right for you, consider these questions: What is the demand for water? (suction, pressure, and flow)? What is the height that you will need to move the water to? Does the pump have to be movable or may it stay in one place? Also, it all depends on how much water you need to pump, how rapidly you need to pump it, and how unclean the water is. Many factors influence pump performance, including atmospheric pressure (how high the pump is above sea level), hose resistance, and so forth. The flow rate of a pump is measured and expressed in gallons per minute or gallons per hour. The higher the flow, the better the performance. If the water is sandy, muddy (abrasive), or contains minute particles, you should get a semi-trash or trash pump. If the water you plan to pump is always clean, such as in a swimming pool, hot tub, or water garden, a clean water pump will suffice.
Q       How to size and choose a Craftop gas water pump?
A       Gas water pumps can be selected based on the desired application and how quickly the water needs to be pumped. GPM/PSI ratings, inlet/outlet size for water and hoses, how high you’ll need to pump the water, referred to as Total Head Lift (measured in vertical feet), and how far you’ll need to pump the water horizontally are the most significant elements in properly sizing a gas water pump. Finally, never use a gas water pump indoors since carbon monoxide will build up from the exhaust fumes, which can be fatal.
Q       Why use a Craftop gasoline water pump
A       Power: Craftop Gas Water Pumps are more powerful and move far more water than other types of pumps. Higher gallons per minute (GPM) and PSI ratings on gas pumps make all the difference in getting the work done in two hours or twenty minutes for heavy-duty applications like flood clearance or emptying a building site. Versatility and Portability: You can take a gas-powered water pump anywhere you need it on the job site, and not rely on having electricity to power the pump. Craftop Gas Water Pumps are a favorite for the agricultural/farming industry because the pumps can be used to power irrigation systems or can be mounted onto tractors and other farm equipment Trash pumps that run on gasoline are powerful enough to be used for pumping solids, debris, and wastewater that could come from flooding or emptying quarries that have small rocks and other materials present in the water, and are a favorite for construction companies or city municipalities.
Q       How does a gasoline water pump work?
A       When the engine starts, the centrifugal impeller rotates, pushing water out of the pump through the discharge port. The displacement of this water then creates a vacuum, drawing water from the tank into the water pump’s inlet side. This procedure is then repeated to keep the water flowing

“This is my NT6210. We are just out of one of the worst storms in living memory here in Ireland. This saw worked for 3 days almost 8 hours a day. My first comment is this saw is very well balanced and constructed. My second comment is it is very economical on fuel. Very happy to recommend this saw to anyone who asks me. Blade is holding its edge very well. Craftop is the Toyota of chainsaws.”
