Business Valuation: Pump Technology

The average Swiss Pump Technology company is valued at 4.0 - 6.0× EBITDA on a statutory (tax-based) basis and 5.5 - 7.5× EBITDA in actual deal transactions. The spread between statutory and deal multiples represents a key arbitrage opportunity for informed buyers. The current market trend is stable, with an arbitrage gap rated as medium. Actual valuations depend heavily on recurring revenue share, customer diversification, management depth, and equipment modernity.

Key valuation drivers include: The customer base is growing even though the sector is not: water supply and sewerage (NOGA divisions 36 and 37) grew employment 31.9% and 45.7% between 2012 and BFS STATENT 2024, while machinery employment stayed flat; A regulated demand driver with decades to run — of the 22 micropollutants with ecotoxicological limits under the Waters Protection Ordinance, 18 exceeded them in 2022 and only 6 of 38 watercourses complied, and advanced treatment needs pumps and dosing. Factors that can compress valuations include: The makers are in the wrong division for growth: machinery exports fell 2.1% in H1 2026 against total tech exports of +1.7%, and NOGA division 28 lost 21.3% of its establishments between 2012 and STATENT 2024; Two of the eight companies listed in the February 2026 edition of this report do not exist in the commercial register, and three of the remaining six were placed in the wrong canton — the published picture of this niche was materially wrong. Deal multiples typically range from 5.5 - 7.5× EBITDA, but actual prices vary significantly based on customer concentration, management quality, revenue predictability, and geographic reach within Switzerland's 26 cantons.

There is no official count of Swiss pump technology companies, and the roughly 650 firms cited here is an estimate rather than a measurement. Pumps have no NOGA code of their own: they sit inside division 28, manufacture of machinery and equipment, and the BFS publishes STATENT only at division level. Division 28 held 1,968 establishments and 79,054 employees in BFS STATENT 2024, published 20 August 2026 — employment essentially flat since 2012 at -1.1%, but the establishment count down 21.3%. The more useful comparison is with the customers: NOGA divisions 36 and 37, water supply and sewerage, grew employment 31.9% and 45.7% over the same twelve years. Swiss pump makers are a contracting-sector supplier to an expanding-sector buyer. The commercial register is the reliable check on any individual name, and here it changes the list substantially. Two of the eight companies in the February 2026 edition of this report do not appear in the register at all: there is no Helios Pumpen AG in Zurich and no Wepuko Pahnke (Schweiz) AG in Romanshorn. Three of the remaining six were placed in the wrong canton: SAWA Pumpentechnik AG is registered in Degersheim (SG), not Burgdorf (BE); Häny AG in Rapperswil-Jona (SG), not Meilen (ZH); and Rütschi Fluid AG in Möhlin (AG), not Brugg. The anchor name is inexact too — the register holds Sulzer AG in Winterthur, with Sulzer Management AG at the same seat, rather than "Sulzer Ltd". Two substantial Swiss names were missing entirely and are added here: Biral AG in Münsingen (BE) for circulation pumps and building services, and ProMinent Dosiertechnik AG in Regensdorf (ZH) for dosing and water treatment chemistry.

Succession in Swiss pump technology is being decided by a business that sits between two diverging sectors. The makers are in NOGA division 28, machinery, where BFS STATENT 2024 shows employment flat since 2012 at -1.1% but establishments down 21.3%, and where Swissmem reported exports falling 2.1% in the first half of 2026. Their institutional customers are in divisions 36 and 37, water supply and sewerage, which over the same twelve years grew employment 31.9% and 45.7%. A buyer will want to know which of those a company's order book actually tracks, and that is a question about the customer mix, not about the product range. Six of the eight companies in this niche are owner-managed or family-held, which makes the question live rather than theoretical. Three things then set the price. The first is the recurring base. A process pump runs for decades under service contract, and spares, seals and overhaul revenue is annuity-like and materially higher margin than the original unit — separating that stream out and showing the installed base with its service attachment rate is usually worth more than any growth argument. The second is application knowledge, which in this niche is unusually concentrated. Selecting a pump for an abrasive slurry, an aggressive chemical or a gas-laden medium is experience rather than a catalogue lookup, and it sits with named engineers who hold the specification position at particular customers; an owner who cannot name the successor for each application area is selling a discount. The third is input cost and its pass-through. Section 232 duties of 10-50% on steel, aluminium and copper have applied since April 2026, and a pump casing, impeller and motor are made of exactly those materials; the US has applied 12.5% to Swiss tech goods since the end of July 2026, and Swissmem reports a quarter of tech industry companies posting negative EBIT margins. Owners should separate service from equipment revenue, evidence the installed base and service attachment, name the successor for each application area, show how metal cost is passed through, and allow two to three years of overlap. Deal multiples for the sector typically run 5.5 - 7.5× EBITDA.

Four trends define the sector in 2026: (1) A contracting-sector supplier to an expanding-sector buyer — Pump makers sit in NOGA division 28, machinery, which BFS STATENT 2024 shows at 1,968 establishments and 79,054 employees — employment flat since 2012 at -1.1% but establishments down 21.3% — with machinery exports down 2.1% in H1 2026 against total tech exports of +1.7%. (2) Two of eight listed companies do not exist, and three more were in the wrong canton — There is no Helios Pumpen AG in Zurich and no Wepuko Pahnke (Schweiz) AG in Romanshorn — neither appears in the commercial register. (3) The corrected map has an eastern Swiss cluster the previous edition missed — Two of the eight companies in this niche are registered in St. Gallen — SAWA Pumpentechnik AG in Degersheim and Häny AG in Rapperswil-Jona — a canton absent from the previous edition's cluster list entirely. (4) Regulated water and building demand is the growth case, and it is documented — The Federal Office for the Environment reports that of the 22 micropollutants regulated with ecotoxicological limits in the Waters Protection Ordinance — 19 pesticides and 3 pharmaceuticals, in force since April 2020 — 18 exceeded their limit in 2022, and only six of the 38 watercourses examined complied.

The principal acquisition risks are: (1) Section 232 duties of 10-50% on steel, aluminium and copper have applied since April 2026, and a pump casing, impeller and motor are made of exactly those materials; (2) US tariff escalation more broadly: 39% in August 2025, capped at 15% in November 2025, and 12.5% on Swiss tech goods since the end of July 2026, 2.5 percentage points above the EU rate; (3) Swissmem reports a quarter of tech industry companies posting negative EBIT margins and a further 29% barely covering cost of capital and R&D — margin headroom in Swiss machinery is thin. Buyers should conduct thorough due diligence on customer concentration, regulatory compliance, and key-person dependencies. Deal multiples of 5.5 - 7.5× EBITDA may be discounted for firms with elevated risk profiles.

The typical cost breakdown for a Swiss Pump Technology firm is: Raw Materials (stainless steel, alloys, castings): 32%, Personnel Costs: 33%, Equipment Depreciation & Tooling: 9%, Energy & Utilities: 4%, R&D and Engineering: 7%, Logistics & Distribution: 5%, Other Operating Costs: 2%, Profit Margin (EBITDA): 8%. Indicative split for a Swiss pump manufacturer. Metals dominate the material line and the tariff timeline lands directly on them: Section 232 duties of 10-50% on steel, aluminium and copper have applied since April 2026, and a pump casing, impeller and motor are made of exactly those materials. On top of that the US has applied 12.5% to Swiss tech goods since the end of July 2026, 2.5 percentage points above the EU rate. Service and spares carry a different economics from the equipment line and should be modelled separately: a process pump runs for decades under contract and the aftermarket margin is materially higher. Swissmem reported machinery exports down 2.1% in H1 2026 against total tech exports of +1.7%, with capacity utilisation of 81.1% in Q2 2026 against a long-run average of 85.6% (2015-2025), while the customer side — NOGA divisions 36 and 37, water supply and sewerage — grew employment 31.9% and 45.7% between 2012 and BFS STATENT 2024. These benchmarks are important for buyers assessing operational efficiency and margin improvement potential post-acquisition.

Switzerland's main Pump Technology clusters are: (1) Winterthur and Zurich (ZH) — The listed anchor and the dosing specialist. Sulzer AG is registered in Winterthur with Sulzer Management AG at the same seat, and ProMinent Dosiertechnik AG in Regensdorf covers metering and water treatment chemistry. (2) Aargau (AG) — Chemical and process pumping. CP Pumpen AG builds magnetic drive and lined pumps for aggressive media in Zofingen, and Rütschi Fluid AG serves process industry from Möhlin — not Brugg, as earlier editions of this report stated. (3) Eastern Switzerland (SG) — A cluster the previous edition did not have. SAWA Pumpentechnik AG is registered in Degersheim and Häny AG in Rapperswil-Jona, both in St. Gallen — a canton that appeared nowhere in the February 2026 cluster list, because both companies were placed in the wrong canton. (4) Western Switzerland and Bern (NE, SZ, BE) — Difficult media and building services. Emile Egger & Cie S.A. builds pumps for abrasive and gas-laden duty in Cressier (NE), with a second registered site as Emile EGGER Wangen SZ AG in Wangen (SZ), and Biral AG makes circulation pumps in Münsingen (BE). Regional concentration affects valuations, as companies in established clusters benefit from supplier ecosystems, specialized talent pools, and industry networks.
