Pump quality
Pump safety: No approval without CE
Tsurumi goes to great lengths to ensure that its waste water pumps are as safe as possible down to the last detail. The use of approved components is mandatory.
One example of efforts that go beyond this is the individually encapsulated electrical conductors in the cable entry: electrical damage such as a short circuit due to moisture penetration is ruled out with this hermetic seal. Unfortunately, the quality of a power unit is not immediately apparent to many users. Many counterfeits from the Far East populate the market. Even experts cannot distinguish them from the original at first glance. Tsurumi recommends taking a close look at the rating plate first. There are five minimum details: Manufacturer, name of the machine, type with serial number if applicable, year of manufacture and CE mark. Incorrect information is not a lapse: if the CE logo is missing, for example, the pump is not approved. The data, for example on electrical power, cannot be relied upon. In any case, the electrical system is a critical point. It starts with the cable. Well-known manufacturers use cables that are VDE-certified and safe. A glance at the sheath labeling can often provide clarity. Top manufacturers, although not all of them, also focus on quality when it comes to "invisible" components. Tsurumi, for example, obtains the fundamentally important mechanical seal for the pump shaft in a double internal design from the market-leading manufacturer of these components. Some components are the domain of the respective manufacturer. In Tsurumi's case, this includes the oil distributor, which was developed in-house and for which a patent application has been filed, and which optimally lubricates the pump in every position. sw
