ECHA's two committees reached a provisional conclusion on PFAS uses in petroleum and mining at their September meeting — the universal restriction is being assessed in sector-sized pieces, and the sealing applications that pumps depend on sit in a block not yet evaluated.

CEN has published the part that tells the market how to rate a booster set — a packaged pump assembly — on one energy efficiency index. The rated object is no longer the pump; it is the machine as installed.

Delete the dynamic shaft seal and the cryogen family — nitrogen, oxygen, argon, LNG, ethylene, hydrogen — all want the same containment. What changes with each liquid is the temperature, and what changes hardest at hydrogen is everything else.

Beneath the 13th edition's structural overhaul, the changes a plant will feel first sit at two interfaces — the nozzle-load tables extended to DN600 with a hardened casing-design rule, and a new high-pressure seal-chamber table extending standardised sizes to 14.

The owner community's supplementary specification for API 610 centrifugal pumps moved to version 2.01 in December 2025 — months before the base standard's own 13th edition arrived — which raises the question every project file now faces: which edition of which layer governs.

ISO published the second edition of ISO 15783 on 7 May 2026 — the first revision of the dedicated sealless-pump specification since 2002 — covering magnet-drive and canned-motor pumps in the class of service where the containment is the design.

The EU is preparing to replace the 2012 regulation that set the MEI 0.40 efficiency floor for clean-water pumps — folding in wastewater and other pump types and scoring the pump, motor and drive as one product — and a June 2026 political agreement has kept the revision on the existing legal track through 2028.

The first revision of the petroleum industry's centrifugal-pump standard in five years arrived in June 2026 — 237 pages replacing the 2021 edition — and the changes a purchaser will feel sit in the nozzle-load tables, a new high-pressure seal-chamber table and a first rule on additively manufactured parts.

ASME issued B73.1-2026 on 31 March 2026, replacing the 2020 edition of the chemical-process pump standard. The designation on a nameplate promises interchangeable mounting dimensions — and says nothing about the hydraulics, the materials or the seal.

A final rule dated 28 March 2026 and published in the Federal Register on 1 April 2026 puts pumps in light-liquid service at chemical manufacturing area sources on annual instrument monitoring for the first time — with a leak defined at 10,000 ppmv and repair deadlines of five and fifteen calendar days.

A first-of-its-kind unit in China's Daqing oilfield turns the pressure of high-pressure rich amine straight into pump drive power, and the figure published with it — a 30% plant-level energy reduction — is a plant number, not a pump number.

China's draft manufacturing conditions for alkaline electrolysis equipment put the stack's power range at 30–120% of rated power and the ramp rate at not less than 20% of rated load a minute. The circulating lye loop is where the gas-purity limits are met — and the draft publishes no pump-level figures at all.

As of September 2026 no PFAS restriction has been adopted in the European Union — two scientific committees have given their opinions, the consultation closed on 25 May, and the final opinion is expected at the end of the year. For a pump specification the live question is narrower: which wetted parts depend on a fluorinated material.

Above 7.38 MPa and 31 °C, carbon dioxide is dense enough to pump instead of compress — and at that duty the volume left in the valve chamber sets the efficiency.

At −253 °C a pump is fighting heat rather than pressure — and two Chinese tests in 2026 put the first public numbers on both ends of the duty.

A molten-salt pump moves a fluid that is liquid only because it is kept hot — and China's standard for that fluid was published in 2024 while the standard for the pump itself only entered the national plan in July 2026.

500 cP is where the recommendation changes, not where a machine stops working — and the gap between those two statements is wider than most specifications assume.

Read the temperature with the letter, never after it — 316L is rated A at 200 °C in one medium and A at 120 °C in another.

Function narrows the list, risk narrows it again, and the material comes third — the order is what stops the answer from moving.
