Lutz-Jesco—Centrifugal Chemical Pump

Centrifugal chemical pumps are used for pumping acid and alkalis and other low-viscosity, aggressive liquids and neutral media. The MB motor pump from Lutz-Jesco 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.

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 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 being dependent on the design of the seal.
