Mechanical seals are carbon ceramic and NBR.  Motor protection is IP55. Single phase motors incorporate an overload protection device.   They can develop high pressures and lifts from comparatively small motors and operate virtually silent, hence they are suitable for many domestic, industrial and horticultural applications. With the addition of a foot-valve, they are capable of suction lifts of 7 metres. They are designed for pumping clean water only up to a maximum of 35ºC. They particularly suitable for systems to be controlled by pressure controllers and inverter drives.
