Mono pump is automatically better

Published: 3-Feb-2001


Lundbeck Pharmaceuticals, which manufactures anti-depressants and organic intermediates, is using a Mono W Range progressing cavity pump with extended hopper to increase process efficiency at its plant in the north east of England.

The W Range pump is on the primary stage of production, where is transfers solid organic matter from the filtration unit to the reactor. The filter cake is discharged into a stainless steel hopper, which is fitted with sprinklers to help re-slurry the solids. The purpose of the system is to recover the organic acid used in the process.

Because the viscosity of the solids is very high, the W Range pump was one of the few able to meet the specifications. Lundbeck previously had to transfer the filter cake from the filter back to the reactor manually, using stainless steel bins.
