What's inside? Review of top models of high-pressure apparatuses (AED)

HOW TO PICK UP AHD AND WHAT TO PAY ATTENTION TO?

The high-pressure apparatus (AED) is the heart of a self-service car wash! Requirements for high-pressure pumps in self-service car washes are, above all, endurance, ease of maintenance and resource intensity. Today, we will single out such companies as INTERPUMP or CATPUMPS from the leaders of pump manufacturers. According to statistics, all TOP companies, self-service car wash manufacturers, focused on these brands.

To begin with, it is very important to understand that at the facilities of car wash self-service, where the capacity of the car exceeds any indicators of the classic hand washes, the AED works in extreme conditions. Therefore, the permissible load for the pump should be no more than 70% of the maximum values. That is, if the AVD at 5.5 kW with a maximum pressure of 250 bar (for example, EVOLUTION3 EB2515 InterPump) operates at a nominal (normal) mode at 140 bar, consuming approximately 4 kW, then the “heart” of the self-service car wash will work declared by the manufacturer. If we take the HAWK NMT 1520 pump (max 15l / 200bar) and start to operate it in the nominal (normal) mode at 170 bar, then the load on the pump will be more than 85% and as a result, the service life will come out much faster than you expect.
