Type D pumps for pumping water in water supply systems of industrial and communal facilities are also used for irrigation and drainage of land.
Purpose: type D and pumping units based on their type of blood pressure are designed for pumping water with a temperature of up to 85 0 C in water supply systems of industrial and communal facilities, reclamation.
Design: Pumps D - centrifugal, horizontal, spiral with a horizontal connector of the case, single -stage with the work wheel of a bilateral entrance. The supports of the pump rotor are supporters of rolling or slipping (depending on the power consumption) with plastic or crankcase grease. Shaft seals - mechanical with a stuffing box stuffing.
Materials:
- hulls, lids and working wheels - castings of gray cast iron;
- Details of slotting seals - unprotected corrosion -resistant alloys;
- shaft - varietal rental made of structural alloy steel 40x.
Complete:
- collected pump;
- Representative flanges on the pipes;
- drive electric motor;
- Connecting coupling type MUVP or MUP with a fence;
- General or separate foundation frames (depending on the size of the pump);
- Parts of fastening the pump, engine and fence of the coupling;
- SIP set.
