Overload Protection

OVERLOAD PROTECTION: It is strongly recommended that all SV & SK non-clog models used for sewage or farm waste are fitted with the overload protection control box. This is designed to protect the pump motor from damage by switching off the electricity supply in the event of the pump becoming jammed by foreign bodies e.g stones etc.

The control box is fitted in a waterproof enclosure with manual stop/start switch and also provides short circuit protection.

JS MODELS: are fitted with a strainer on the inlet and can be operated without overload protection, although it is a wise precaution particularly when pumping water with a high ratio of sediment.

There is a 10mtr cable between the pump and control box and a further short cable from the control box for mains connection.

OUTLET PIPING: For ease of installation a length of flexible hose can be fitted between the pump and the main outlet pipe. 3 mtrs reinforced flexible 2” hose complete with couplings to pump, quick release lever couplings and outlet pipe compression couplings. (please state diameter of main pipeline when ordering). £85.00

NON-RETURN VALVES: are not normally necessary when pumping from larger settlement tanks, slurry pits etc. When pumping from small collection pits and in most domestic sewage systems a non-return valve will usually be required to prevent run back from reactivating the float switch.
