BASF - A MAJOR MULTINATIONAL
Issue: Replacement of a Centrifugal imported pump.
BASF manufactures synthetic tanning agents for which they use high pressure spray driers. One such spray drier used a high speed Centrifugal imported pump which was continuously malfunctioning resulting in replacements of bearings and mechanical seals which are quite expensive apart from the down-time required to carry out the replacements.
After studying the requirements and the operations we specifically developed and delivered a High Pressure Triplex Sandwich Diaphragm Pump model TP80SD which is sealless and glandless. Two such Pumps are installed at Tamil Nadu Paper Mills Limited.
Having the confidence in the product, BASF ordered three more pumps for similar applications. Due to the higher efficiency of the reciprocating pumps, BASF experienced considerable savings on consumption of electric power.
NOCIL - INDIA'S LEADING PETROCHEMICAL COMPANY. (NOW A PART OF RELIANCE GROUP)
Issue: Engineering a solution for caustic leakage.
NOCIL were using Plunger Pumps for caustic application. Plunger Pumps have gland packings, which are supposed to leak. Caustic leakage was making the site messy and also gland replacement was a perennial maintenance requirement.
Our Engineers recommended use of Hydraulically Actuated Diaphragm Pumps. The existing Plunger pumps were converted to Hydraulically Actuated Sandwich Diaphragm pumps.
Currently the site is very clean and the diaphragms changed as per stipulations. The maintenance personnel are now pleased with the solution that was provided.
LIQUID CO2 INJECTION FOR PLASTIC FOAM SHEETS
Foam sheet pads are required in ROPP & Crown caps. High pressure liquid CO2 has to be injected into the extruded film. All extruders were originally fitted with imported pumps. The flow accuracy requirement is very high and discharge pressure is between 200 bar to 300 bar.
Metallic Sandwich Diaphragm pump with three heads was developed to give small flow with high accuracy and negligible pulsation. Several such installations are working successfully.
SMALL CAPACITY HIGH PRESSURE AUTOCLAVE APPLICATION
There is a requirement for Laboratory Autoclaves for high pressure metering pumps with very low capacity typically 1.0 to 0.5 lit / hr @ 100 to 180 bar.
Specially designed Metallic Sandwich Diaphragm Pumps for low flow applications were supplied. Several such installations are working successfully.
PUMPS FOR CERAMIC SLURRY SPRAY DRYER
Ceramic slurry has to be sprayed thru nozzle in the spray dryer. Ceramic being highly abrasive, needs specially designed diaphragm pump. Most of the plants had imported pumps.
Hydraulically actuated sandwich diaphragm pump with special NRV’s was developed successfully. Several customers have given repeat orders for these pumps to replace imported pumps.
