The self-service car wash pump used by Washercar

In this article, we will tell you about the main advantages and differences of the Interpump E3B-2515 high-pressure washer.
Most often you can find 3 manufacturers of pumps:

  • Cat
  • Hawk
  • Interpump

Why did we choose Interpump, whose pumps we use in the manufacture of equipment?

Interpump is an Italian company and their pumps combine many years of

years of experience, modern technologies with unique patents, time-tested materials and high-precision robotic assembly with high quality control standards. All this makes the finished product as reliable and easy to maintain as possible. This is very important in the harshest operating conditions at self-service car washes.

Main advantages:

  • Die-cast, brass and stainless steel head body. The quality material of this part is important and directly affects the service life of the product as a whole.The pump is tested at a maximum pressure of 450 watts.
    Increased size of the pump crankcase and, accordingly, the volume of oil in the crankcase, which allows to generate more heat from the rubbing elements and increase lubrication functions.
    Durable, thick-walled ceramic piston made of Japanese ceramic powder and baked in an ultra-high pressure chamber. Incredibly reliable element made of salmon steel, eliminating the appearance of cracks and chips and withstanding overheating.
  • Graphite piston guide system. The patented pride of Interpump, it ensures optimum piston guide sliding and minimizes friction between the piston and the gate valve and extends the service life of this group of elements.
    Compact, space-saving crank mechanism. With reduced vibration masses, high sliding coefficient and innovative materials. All this makes the pump itself quiet and virtually silent in operation.
    Double lump oil seal. It guarantees an improved oil seal and significantly increases the service life compared to analogs.
    The sealing package consists of a high-pressure oil seal and a water seal. These components are available in different versions, which differ in their service life before replacement. As well as temperature conditions, this unit is made as a complex, which speeds up and ensures service replacement.
  • The 44 series valve. Here we can see the high side mechanism with a reduced diameter, which allows for an even distribution of the action force and an increase in the service life of the valve group. And the inlet valve, on the contrary, has an increased cross-section, which allows the pump to easily take in water in full, without resistance. In general, we would like to single out this Interpump valve group and say a special thank you to them, because this solution elevates the pump to a level above any competitor.
    Reinforced roller bearing. It has a huge resource and serves throughout the entire service life of the pump.
    We also want to note the convenient viewing window, through which you can perfectly observe the level and quality of the oil.

This model of the pump is filled with 750 ml of specialized Italian oil, which prevents all unscheduled maintenance work, removes excess moisture and regulates the efficiency of the pump.

All this makes this pump the undisputed leader in the installation of self-service car wash equipment, and millions of facilities already in operation confirm this.
We would also like to note that in the PRO+ kit we use the latest pump from Interpump S3W. This pump is even more advanced. Its main differences are a cast stainless alloy head, an alloy crankcase and even more reinforced, thick-walled pistons. That puts this pump out of competition.

And remember, the pump is the heart of self-service car wash equipment.
