Industries

Built for the plants that are hardest on pumps

Twenty-three industries in four families. Each line shows the pump series our customers in that industry use.

Chemical & process

Applications

Three duties we know best

Leakless AGP multistage liquid ammonia pump with green motorLeakless LCMP canned motor pump in blue
Cold storage, ice plants, frozen food and chilling

Liquid ammonia

Ammonia leaks are a safety incident, not a maintenance job. Our AGP pumps circulate liquid ammonia down to −60 °C, and the canned motor LCMP has no seal at all.

  • AGP Liquid ammonia pump
  • LCMP Canned motor pump
Leakless LCP centrifugal pump with white polypropylene casing on a blue baseLeakless LCP back pull-out pump with black PVDF casing and blue bearing frame
Chemical, fertilizer, pickling and electroplating plants

Acid transfer

Polypropylene and PVDF pumps for sulphuric, hydrochloric and nitric acid duties, with PTFE bellow or multi-spring seals chosen for the concentration and temperature.

  • LCP PP / GFPP / UHMW-PE centrifugal pump
  • LCP PVDF / PTFE-lined back pull-out pump
Leakless LVGP vertical glandless pump with white casing and green motorLeakless LSP self-priming pump with tall black priming chamber
Fume scrubbers, ETPs and pits

Scrubbers and effluent

Vertical glandless pumps for scrubber liquor, and self-priming pumps that lift effluent from pits without a foot valve.

  • LVGP Vertical sealless glandless pump
  • LSP Self-priming chamber pump
Tested before it leaves

Every pump runs on our test bed before it ships

Each assembled pump is pressure-tested and run against its rated duty in our Mumbai works. You get the readings with the pump.

  • Hydraulic pressure test of seal, volute casing and casing cover
  • Pin-hole porosity check on castings
  • Running test for discharge head and flow
  • Power and speed (rpm)
  • Vibration and noise level
  • Bearing housing temperature
  • Mechanical seal leakage
  • Physical and chemical material certificates from outside labs
