Pumps shall be equipped with UL listed, Class I, Division 1, Groups C and D; Class II, Division 1, Groups E, F and G Drive Assembly. Output volume shall be adjustable while pumps are in operation from zero to maximum capacity.

    Pump Controls

    The pump drive shall be totally enclosed with no exposed moving parts. Pump drives shall be UL listed Class I, Groups C and D and Class II, Division 1, Groups E, F and G. Solid state electronic pulser shall be fully encapsulated with no exposed printed circuit etch and with quick connect terminals at least 3/16" (4.75 mm) wide. Electronics shall be housed in chemical resistant enclosure at the rear of the pump for maximum protection against chemical spillage. Average electrical power consumption shall not exceed 44 watt hours per hour under full speed and maximum pressure conditions. Pump weight shall not exceed 41 lbs (18.6 kg).
