The ES range from E-Tech are AISI 304 stainless steel pumps with a built in check valve, built-in capacitor, double mechanical seal and fully waterproof electronics. The pumps all come with 20m of power cable which is a plug-in type so it can be easily replaced. The design ensures that no routine maintenance is required and the pump can be permanently submerged. The MA versions are also equipped with a float switch which stops the pump automatically when there is no water.
