About this item
Efficient Drainage
High-efficiency water utility pump with 1HP power motor. Draining water up to 3960 Gallons Per Hour( 66 gallons per minute) at 5ft. Lift water up to 31ft of vertical height.
Portable and Convenient
The water pump is made of thermoplastic material, which reinforces its durability and corrosion resistance. Unique ergonomic handle and hollow design for easy portability. Compact size and lightweight for easy storage fits household and outdoor occasions.
Wide Applicability
This water pump is great for clean or dirty water from swimming pool covers, basements, pits, ponds, window wells, rain barrels, or other flooded areas. The pump is also perfect for irrigation, garden watering, car washing, and other home requirement.
Easy Installation
A water pump can be operated easily by plugging into the power supply, which has a 1-inch NPT discharge and includes a hose adapter that fits 1-1/2, 1-1/4, or 1-inch hose.
Safety Ensure
The water pump provides high-efficiency draining performance and ensures long service life. A built-in automatic thermal overload protector will protect the pump from overheating damage. Our pump comes with a 1-year warranty, please do not hesitate to contact us.
We have to remind you:
- This water pump is designed to handle clear water. Any of the following can clog the pump or damage the pump system:
A physical obstruction such as sand, dirt, debris, or water scale/rust.
Caustic liquids like salt water, brine, laundry discharge, or any other liquid containing caustic chemicals and/or foreign materials.
Flammable or explosive fluids such as gasoline, fuel oil, kerosene, etc.
- Do not run the pump dry. Before using it for the first time, or before reusing it after a long time has elapsed, add an appropriate amount of clean water from the pump head water inlet. Water injection is to lubricate and make the space sealing better.
- This water pump is not a submersible pump. Do not submerge it in water or other liquids.
- When the water pump runs for a while, the pump will become hot (the temperature is generally around 55 ° C). This is normal, please don't worry.
There are many kinds of pumps. Here we introduce the most basic "centrifugal pump", whose structure is as follows:
Working principle of centrifugal pump
The liquid rotates with the impeller and moves outward along the channel between the blades under the action of centrifugal force. The speed increases and the mechanical energy increases. The liquid leaves the impeller and enters the volute, the volute channel gradually expands, the fluid speed slows down, the liquid kinetic energy is converted into static pressure energy, the pressure increases continuously, and finally flows out of the volute tangentially through the conduit.
Operation of centrifugal pump
(1)Preparation before the operation
Check the valves, flange anchor bolts, couplings, thermometers, and pressure gauges on the pump inlet and outlet pipelines.
Check the operation of the pump, turn the gear first, listen for noise, and see if it is flexible.
Open the inlet valve, discharge the gas in the pump, fill the pump with the liquid to be delivered, and then close the outlet valve.
Fill the oil tank of the pump with lubricating oil or grease.
Give cooling water and turn on the pressure gauge to see if it is sensitive.
Check safety equipment, such as wheel housing, grounding wire, etc.
Check the preheating condition of the hot oil pump so that the temperature of the pump body cannot be lower than the boundary temperature by 40 ℃.
Contact relevant posts and units. Prepare for a startup.
(2)Normal startup
The pump can be started after the preparation is checked to be normal. After starting, pay attention to the ammeter, pump steering, pressure gauge, leakage, and other conditions, and then slowly open the outlet valve after everything is normal.
(the pump shall not operate for more than 3 minutes before opening the outlet valve, otherwise, the temperature of the liquid will rise after the forced circulation in the pump, and the vaporization of the liquid will produce evacuation and other phenomena.)
Check that the bearing temperature of the pump shall not be greater than 65 degrees and the motor temperature shall not be greater than 70 degrees.
The flow can be adjusted by the pump outlet valve.
Observe the fluctuation of the outlet pressure gauge and ammeter.
Check the operation, vibration, and leakage of the pump.
Check the supply of pump cooling water and the change of lubricating oil level.
For the pump with sealing oil, the sealing oil pressure shall be at least 0.05-0.1mpa higher than the pump outlet pressure.
For the long-term operation of the pump, the lubricating oil or grease should be replaced regularly to ensure that the pump works under good lubrication.
(3)Stop
Slowly close the outlet valve.
Cut off the power supply and close the inlet valve and pressure gauge valve.
Hot oil pump, stop cooling water and sealing oil after the temperature of the pump decreases.
In winter, discharge the liquid in the stopped pump and take necessary anti-freezing measures.
Regular inspection and turning.
Application field
① In the production of chemical and petroleum sectors, most of the raw materials, semi-finished products, and finished products are liquids, and the production of semi-finished and finished raw materials into semi-finished products and finished products needs to go through complex technological processes. During these processes, pumps play a role in transporting liquids and providing pressure flow for chemical reactions. In addition, in many installations, pumps are used to adjust the temperature.
② In agricultural production, pumps are the main irrigation and drainage machinery. my country's rural areas are vast, and a large number of pumps are needed in rural areas every year. Generally speaking, agricultural pumps account for more than half of the total output of pumps. Pumps are also the most used equipment in the mining and metallurgical industries. The mine needs to be drained by pumps, and in the process of beneficiation, smelting, and rolling, pumps are needed to supply water.
③ In the power sector, nuclear power plants need nuclear main pumps, secondary pumps, and tertiary pumps, and thermal power plants need a large number of boiler feed pumps, condensate pumps, oil and gas mixing pumps, circulating pumps, and ash pumps.
④ In national defense construction, the adjustment of aircraft flaps, tail rudders, and landing gear, the rotation of warships and tank turrets, and the ups and downs of submarines all require pumps. High pressure and radioactive liquid, and some also require the pump without any leakage.
⑤ In short, whether it is aircraft, rockets, tanks, submarines, drilling, mining, trains, ships, or everyday life, pumps are needed everywhere, and pumps are running everywhere. That's why the pump is listed as a general-purpose machine, which is a major product in the machinery industry.
⑥ Electric pumps i.e. pump driven by electricity. The electric pump is composed of a pump body, a water lift pipe, a pump base, a submersible motor (including cables), and a starting protection de
