About Interpump

Interpump Group S.p.A. is the world's largest manufacturer of high-pressure triplex plunger pumps, with over 45 years of continuous R&D focused on industrial cleaning, cooling, and fluid-handling applications. The available range spans the full W-series (home-use through industrial), WS-series (stainless steel for food and pharma), TSX-series (ATEX zone-2), and the heavy-industrial HT line — plus pressure-washer assemblies, regulating valves, and spare-part BOMs.

Interpump pumps drive three distinct application families: industrial cleaning (shipyard hull wash, petrochemical heat-exchanger descaling, concrete surface prep), process cooling (mist-cooling for outdoor HVAC condenser decks, textile fibre-finishing spray lines), and high-pressure chemical injection (reverse-osmosis permeate boost, municipal water-treatment disinfection loops). Frequently-specified models include the W951 (15 L/min @ 200 bar), the HT100 (50 L/min @ 350 bar for industrial-duty cleaning), and the ZP560 ATEX spray-gun assemblies for zone-2 petrochemical use.

Seal kits, valve assemblies, plunger sets, and crankshaft rebuild kits for the most-common Interpump models are available for prompt supply. Typical in-service rebuilds (full seals + valves) turn around inside a week, and service loaner pumps can be swapped in during the rebuild window for critical-path installations.

Common Applications

  • Shipyard hull cleaning and surface prep — HT100 and W951 paired with dual-lance guns for dockyard service
  • Petrochemical heat-exchanger descaling — WS-series stainless pumps for neutral-pH cleaning chemistry
  • Outdoor HVAC condenser mist cooling — ZP180 pumps on rooftop chiller decks
  • Textile fibre-finishing — W170 and W270 for mist-jet application across drying lines
  • Municipal water treatment — W951 motor pumps for high-pressure disinfection chemical injection

Frequently asked questions

Common questions about Interpump from 3G Electric.

Are Interpump products and spare parts available?

Yes. We supply genuine Interpump pumps and spare parts with full manufacturer warranty.

What is the lead time for Interpump W951 and HT-series pumps?

Complete pump units have a factory lead time on request. The most commonly-ordered spare parts (seal kits, valve assemblies, plunger sets) for W, WS, and HT series are typically available on shorter lead times.

Can you supply Interpump ATEX / zone-2 rated pumps?

Yes — we distribute the full TSX and ZP-ATEX ranges certified for ATEX zone-2 petrochemical and marine use. Common specs for shipyard and refinery customers include TSX961 motorpumps and ZP560 spray-gun assemblies with 500/750/1000 mm lances.

Do you rebuild Interpump pumps on-site?

Yes. Our workshop handles full rebuilds (seals, valves, plungers, crankshaft inspection). For critical-path installations we can swap in a service loaner pump during the rebuild window.

Which Interpump model is right for my application?

We size Interpump pumps against flow (L/min), pressure (bar), duty cycle, chemistry, and zone classification. Send us your process parameters via the RFQ form and our engineers will return a sized proposal with a comparable catalog alternative.

Who distributes Interpump pumps in Singapore?

3G Electric is the authorized Interpump Group distributor in Singapore and Southeast Asia.
