The erection height of the pump, that is the vertical distance
from the sucked liquid surface to the pump shaft should be less
than it which should be taken into consideration for users to se-
lect the pump, is calculated per the following formula:
Hsz Ha-Hv- Hs-(NPSH)r
Of which:
Hsz-- the erection height set with the pump(m)
Ha--- the head of the atmospheric pressure under the
conditions on the spot of use(m)
Hv--- the head of the vapourized pressure under the tem-
perature of the liquid being umped(m)
Hs-- the lost head of the suck-in pipeline(m)
(NPSH)r-- the necessary value of NPSH given in the ta-
ble of performance parameters(m)

Model MD pump consists of four parts, stator, rotor, bea-
ring and shaft seal:
1.Stator consists of inlet, middle and outlet sections and
the guide vane etc., with the take-up bolt tightly clamping
all sections to form a working room. The inlet of it stands
horizontally while the outlet vertically upward.
2.Rotor consists of the shaft, impeller, balancing disk and
muff etc., the shaft passes the power to the impeller to have
it work; the balancing disk balances the axial force; and
replaceable muff is mounted on both sides of the shaft to
protect it.
3.There are rolling and sliding bearings:
The rolling bearing consists of bearing seat, bearing and
bearing gland and uses grease for lubrication.
The sliding bearing consists of bearing body and cover,
liner, dust-proof disk, oil leveller, oil throwing ring etc., and
uses thinned oil for lubrication.
4. The shaft is sealed with stuffing and the shaft seal consi-
sts of the sealing contents, stuffing, baffle. The liquid in
the sealing work-room functions water-sealing, water-
cooling and water lubricating and the water for water-
sealing comes from the pressure water inside of the pump.
In addition, the pump is directly actuated by the prime m-
over through the elastic clutch and, viewing from the prime
mover, moves CW.
