Seim

What Seim does

SEIM s.r.l. is an Italian privately held industrial pump manufacturer founded in 1975 and headquartered near Milan (Cusago, MI), employing between 51 and 100 people. The company specializes in twin and triple screw pump technology, designing and producing its entire product range in-house, including screw pumps, heat exchangers, chillers, double pump stations, flowmeters, and valves. The portfolio spans four operating divisions — Industrial, Marine, Lift, and Oil&Gas — with API676/API614/API682 compliance for upstream through power-generation applications and marine classification society approvals from ABS, RINA, Bureau Veritas, DNV, Lloyd's Register, and CCS for naval use.

The business model rests on three revenue streams: (1) direct sale of configured and custom-engineered screw pumps to OEMs and end users across the four divisions; (2) the SEIM Spares aftermarket division (founded 2017) selling original spare parts and components, including for legacy/discontinued models; and (3) technical service and field support delivered from Italy and through its global distributor network. Pricing is opaque (quote-based B2B industrial sales), and the company states that millions of its pumps are in operation globally.

Distribution combines direct enterprise sales managed from the Italian headquarters (overseen by a CCO and Industrial & Marine Sales Team) with official distributors in France (ESP Groupe), China (Shanghai Hugo IND), India (PUMPSQUARE SYSTEMS), Korea (SEIM KR CO. LTD — wholly-owned subsidiary), and the USA (SHANLEY PUMP), plus a broader agent and service-point network. The company markets via international trade fairs (SIMTOS, IMTS, Posidonia, Gastech, EMO Hannover, Interlift, etc.), a multilingual technical blog on screw pump applications, and a LinkedIn corporate presence. SEIM has been UNI EN ISO 9001:2015 certified since 1995 and is pursuing ISO 14001 environmental certification.

Core offering

Seim manufactures and sells twin and triple screw pumps, heat exchangers, chillers, double pump stations, flowmeters, and valves for fluid handling in industrial, marine, lift, and Oil&Gas applications. The company produces its entire range internally in Italy, offers API676/API614-compliant and marine-class-certified designs, and supplements equipment sales with aftermarket spare parts (SEIM Spares) and technical field service.

Product overview

SEIM is an Italian industrial pump manufacturer offering a comprehensive portfolio of screw pump products and complementary equipment. The core product line consists of twin screw pumps (ASTRA-A, ASTRA-B, 2SP) for high-flow transfer and lubrication applications, and triple screw pumps (PCXA, PWO, PZ, PXF, PA, PB, PCXAO, POC, PWE, PBE, PWOF, PXFCR, PXCA, PDA) serving industrial, marine, lift, and Oil&Gas sectors. Supporting the pump portfolio are heat exchangers (NEG Standard), chillers (MCH1) for hydraulic lift cooling, double pump stations (SPB) for diesel engine applications, flowmeters (MPV2) for high-pressure flow measurement, and valve products (BVPA, EV3, VCP, VMP, VMPI) for pressure control and fluid routing. The product range is organized into four divisions: Industrial (general fluid handling), Marine (naval applications with class certifications), Lift (hydraulic power pack cooling), and Oil&Gas (API-standard compliant pumps for upstream, midstream, and downstream applications).
