Piston diaphragm pumps from ABEL are helping Russia ’ s ALROSA with its filtration process at one of its diamond mines in the country . In Spring 2021 , ABEL received an order for the delivery of six of these piston diaphragm pumps , HM pumps , following an initial HM pump order in 2020 . This inaugural pump was delivered to ALROSA in February 2020 as replacement for a centrifugal pump previously used for filter press feeding . At the beginning of August , the ABEL pump was commissioned at the diamond producer ’ s plant . The dewatering result ( higher solids content , shorter filtration time ) was so convincing that ALROSA decided to feed all filter presses in this plant with the pumps , ABEL said . The latest delivery is being facilitated by ABEL ’ s official distributor in Russia , SibComplectService .
ABEL ’ s HM pumps are available as single- or double-acting versions . They come with a high flow rate , reliable function and particularly low operating and maintenance costs , the company www . im-mining . com

says . In addition to filter press feeding , the hydraulic diaphragm pumps are also used for sludge transport , spray dryer feeding , rotary kiln feeding , autoclave feeding , and sealing / rinsing water supply , among other applications .
In new products , the HMQ-M-80-2000 model is part of the ABEL HMQ series and is described as a " real all rounder for mining applications with high overall efficiency ." The pump is suitable for applications up to a maximum of 8 bar ( 116 psi ) or 250 m 3 / h . The company states : " Because of its benefits like low wear and high reliability at a high efficiency , the new HMQ model is a perfect choice for mining applications . As HMQs can pump conventional and thickened slurries as well as pasty products with a solids content of up to 75 %, it is suitable for applications like filter press feeding , thickener
underflow , backfilling and tailings transfer .”
Lastly , ABEL recently went through a major ownership change as on March 11 , IDEX Corporation completed its previously announced acquisition of Abel Pumps , LP , and certain of its affiliates including ABEL from Hillenbrand , Inc . “ We welcome ABEL and its employees worldwide to the IDEX family of businesses . We look forward to their expertise complementing the longstanding strength IDEX has in pump and valve manufacturing ,” IDEX Chief Executive Officer and President Eric Ashleman said . “ As part of our great team , together we will further expand our abilities to solve customers ’ toughest fluidics challenges .”
