Appointment

Pumps of the D type and pump units based on them of the AD type are designed for pumping water with a temperature of up to 85°C in water supply systems of industrial and municipal facilities, land reclamation.

Structure

Pumps D - centrifugal, horizontal, spiral with a horizontal housing connector, single-stage with a two-way inlet impeller. The pump rotor is supported by rolling or sliding bearings (depending on the power consumption) with plastic or crankcase lubrication. Shaft seals-mechanical with stuffing box.

Symbol name

Materials

housings, covers and impellers – castings made of grey cast iron;

slotted seal parts – non-lockable corrosion-resistant alloys;

shaft – long products made of structural alloy steel 40X.
