Motor pump units MB
General
Centrifugal chemical pumps are used for pumping acid
and alkalis and other low-viscosity, aggressive liquids
and neutral media.
The MB motor pump is a single-stage, normal-priming
centrifugal pump in block design with horizontal axis.
The MB pump has an open impeller for low-viscosity,
acid and alkaline solutions with low solid matter content.
The pump head assembly consists of high-quality plastic
materials with hydraulically efficient spiral casing.
Description of mechanical seal
Mechanical seals basically consist of two perfectly
plane surfaces. One surface rotates with the shaft,
while the other is stationary.
The sealing effect is achieved by the direct contact
between the two plane surfaces. The stationary counter-ring
is normally fixed in position. The sliding ring is able
to move axially and radially in
order to compensate the shaft deflections during operation.
This axial mobility enables mechanical seals to be fitted
within practicable manufacturing tolerances, the accuracy
required being dependent on the design of the seal.
