DryMax diesel diaphragm water are automatic priming, diaphragm pumps with Yanmar L48E electric start engines. They are fitted with nitrile rubber diaphragms and check valves, so priming is unnecessary and indefinite dry running is permissible. Designed for site pumping, they are suitable for fluids containing sand, mud, sludge and suspended spherical solids up to 40mm. Heavy duty, yet lightweight, the pump ends are in aluminium, they use needle bearings and have oil filed gear units. For ease of access and storage the design features a pivoting pump chamber for use sideways or frontwards. Enhanced site-use features include a long run, 5.4litre (6 hour) fuel tank, BSP male connections, 2 wheel site trolley, mud plate, rubber engine mounts and stand by engine recoil. Both models are supplied with a suction strainer and a battery, but hose couplings, washers, clips and hoses are extra. A quick release cam coupling kit, with heavy duty hose clamps, is an optional extra for operator convenience. DryMax 3 diesel diaphragm pump has 3" outlet and inlet while DryMax 2 has 2" inlet and outlet. Maximum suction lift is 8 metres, however 6 metres, or less, is recommended.
