The winspan high-pressure plunger pump adopts forged brass pump head and solid ceramic plunger to provide long-lasting and stable power for industrial cleaning equipment. As the source manufacturing plant of high-pressure washer pump, it winspan eliminate the middleman link and provide mass customization to ensure competitive ex-factory price and fast delivery.
suitable for cleaning equipment manufacturers looking for stable high-pressure power core, providing them with standard high-pressure pumps that meet various power and speed requirements, and supporting modular integration and direct assembly.
Provide one-stop design, development and shell OEM production services for brands that need to OEM the whole machine or customize the appearance, flange size and performance.
suitable for construction units that need to frequently replace the core components of high-power equipment, providing them with plunger pumps that can be replaced immediately and with high durability to ensure that long-term heavy-load cleaning operations are not interrupted.
for the global high-pressure cleaning equipment spare parts wholesale distribution network, to provide a very high general adaptability, factory quality inspection reports and price advantages of the pump core spare parts inventory.
high-density forged brass material, tensile strength to enhance the 30%, can withstand the impact of high-pressure water flow, eliminate the risk of cracks and extend the service life of the pump body.
choose 99% high purity solid ceramic plunger, surface roughness is less than 0.1 microns, greatly reducing the wear of the seal ring, continuous operation time increased by 1000 hours.
The anodized aluminum alloy crankcase is equipped with a large-capacity oil chamber, which can achieve full lubrication at 1450 speeds, reduce the operating temperature by 15 degrees, and avoid dry wear of mechanical parts.
equipped with wear-resistant nitrile rubber and Teflon double sealing system, the pressure-bearing capacity is improved 40%, zero leakage under high pressure is ensured, and the maintenance frequency in the later period is reduced.
one-way valve and valve seat are made of 304 stainless steel and hardened to improve corrosion resistance, withstand high-frequency opening and closing, and ensure long-term stable water flow without fluctuations.
high-precision central shaft hole and standard connecting flange, with tolerance control within 0.02mm, can be seamlessly assembled with various standard motors and engines.

winspan high-pressure plunger pump in the manufacture of the core components of the vertical integration. Through the self-built precision manufacturing factory, the accessories of each high-pressure pump, from crankshaft machining, pump body casting to precision grinding, are completed under strict tolerance control. This makes our products in the long-term high-pressure operation, vibration and noise level than the same industry reduced by a 15%, to ensure the smooth operation of the machine. Unlike similar products on the market that generally use cast iron pump heads or low-purity ceramic-coated plungers, winspan insist on using forged high-strength brass and high-purity solid ceramics. With the unique double anti-leakage sealing structure, the overall service life is greatly extended. At the same time, the factory direct sales model eliminates the intermediary fees of traders and can provide buyers with highly competitive batch solutions.
the winspan crankcase adopts dynamic balance and high precision calibration, and the vibration amplitude is reduced by 20%, which solves the problem of joint fracture caused by excessive vibration of the high-pressure cleaning machine.
winspan the use of high-purity solid ceramic plunger, no coating peeling hidden trouble, solve the ordinary pump due to coating off scratch seal ring caused by frequent water leakage problem.
winspan high-precision matching of the one-way valve and the unloading valve, the pressure relief reaction time is shortened, which solves the problem of cavitation and pressure suppression and damage of the pump head when users frequently switch the water gun.
check the crankcase oil level before use to ensure that the oil is in the center of the red dot of the oil sight glass. The oil needs to be replaced for the first 50 hours of operation.
before starting the pump, the water source must be connected and the air must be exhausted. No idling without water is allowed. The water intake flow must reach more than 1.5 times of the pump calibration flow.
connect the input shaft of the pump with the motor or engine to ensure the speed matching. It is forbidden to run beyond the rated speed to avoid damage to the pump parts due to excessive temperature.
after the work is finished, turn off the power source first, then pull the spray gun wrench to release the residual high pressure in the pipeline, and drain all the water in the pump during the freezing season.
