The pump must always be installed above the water level!! If the pump is set below, the back-flowing water can cause an electrical short circuit.
The pump should be installed at least 10 cm higher than the foundation on a stable platform. If installed on an unstable base, noise from virations can result.
The pump must be located on a levelled platform to prevent biased strain on the diaphragms that could lead to reduced component life of the blower.
Ensure that the unit has good ventilation, especially when subjected to servere operating conditions. If installed in a control cabinet, sufficient ventilation (louvered vents) is essential to prevent overheating. A cool ambience will ensure longer diaphragm and valve life!
The Secoh pump shloud not be operated in a dusty environment. The life of the diaphragms and valves may be shortened by overheating due to easily blocked filter elements. Where the air is dirty, corresponding filters should be provided.
The Secoh pump are weatherproof. However, they should not be exposed to direct sunlight, rain or snow.
The Secoh pumps were specially developed for transporting air. The atmonsphere humidity should not be higher than 90%. Inflammable or aggressive gases and vapors should not enter the pump as the flow path leads to current-carrying parts. A requirement for transporting gases or vapors is that the medium has been previously tested to their resistance and operating safety. This test must take place on the initiative of the user. Secoh accepts no responsibility.
Select tube size, lengths and accessories to keep the pressure loss as small as possible, in particular:
- Make the piping as short and straight as possible
- Do nor use tubing of smaller diameter than the port of the unit (inside Ø min. 19 mm, respective 27 mm for EL twin system).
- Utilize large valves of smaller diameter than the blower's connector port. Use check valves that provide the lowest pressure drop rather than spring loaded valves.
- Select low air loss diffusers for aeration.
Apart from occasional filter cleaning and the simple replacement of some components, such as broken diaphragms, long-termin maintenance-free operation is ensured. Complete repair kits available.
The pumps may not be stored at less than -10°C. The permanent magnet would be weakened in such a case, and the performance would not be expected.The pump may not be stored in direct sunlight or at high temperatures. The rubber parts would age too quickly.
