A new 700 bar petrol-engine hydraulic power unit such as the HYDR'AM MGHT 2A series lists in the compact-utility tier with a 1 L tank, 2 kW nominal power, and 0.65–2 L/min two-stage flow [S1]. At the engineered end, AC-motor clamping units with 11 L tanks, 0.9–4.5 L/min flow, and EN ISO 13851 two-hand console logic sit in a higher band [S3]. Across catalogs active in 2026, indicative offers range from roughly USD 100 for a manual/electric dual-purpose pack to USD 1,000 and above for an AC-motor industrial unit shipping from Shanghai [S5][S10].
The global hydraulic power unit market was valued at USD 12.4 billion in 2022 and is projected to reach USD 21.9 billion by 2032 at a 5.9% CAGR, framing price moves against a steadily expanding installed base [S7]. Stationary HPU offerings on the major B2B portals run across 34 manufacturers and 74 catalog products, meaning buyers are comparing real spec sheets rather than generic price points [S4].
Cost drivers that move the line item
Pressure class is the first lever: 150–250 bar clamping units use commodity gear pumps and mild-steel reservoirs, while 700 bar two-stage packs need a low-pressure/high-pressure pump pair, higher-pressure relief valves, and burst-rated fittings, which is why the HYDR'AM GHTI 2S reaches 700 bar with a 2.4 L/min first stage tapering to 0.5 L/min at peak [S2]. Flow rate scales cost almost linearly because it determines pump displacement, motor frame size, and reservoir turnover. Tank capacity, motor type (single-cylinder 4-stroke petrol versus AC induction), and noise/soundproofing add separate multipliers — a soundproofed cowling alone distinguishes the GHTI 2S "low-noise" variant from the open-frame MGHT 2A at near-identical pressure [S1][S2].
Certification and safety electronics stack on top: a clamping unit with two-hand operator console logic to EN ISO 13851, mushroom pushbuttons with 0.5 second simultaneity, and a 300×400×155 mm control box is materially more expensive than a basic pump-and-tank assembly [S3]. Volume tier, country of origin, and raw-material surcharges (steel, copper windings, cast-iron pump housings) further move the quote; a Made-in-China dual-purpose HPU at USD 100 with 1-piece MOQ versus a Shanghai-shipping AC-motor power unit at USD 1,000 with 1-piece MOQ shows the same MOQ but a 10× price gap tied to pressure, flow, and certification [S5][S10].
Price tiers mapped to spec bands
Entry tier (around USD 100–300): manual/electric dual-purpose packs and 700 bar mini petrol-engine units with 1 L tanks and 0.65–2 L/min flow. The MGHT 2A fits here with a 98 cc single-cylinder 4-stroke petrol engine, 1.2 L petrol tank, 2.1 L oil capacity, and 500×320×440 mm envelope at 27 kg class [S1]. Mid tier (roughly USD 300–800): low-noise petrol packs such as the GHTI 2S with a 3 L oil tank, 27 kg weight, and 2.4/0.5 L/min two-stage flow at 150/700 bar, marketed for site work where dB limits matter [S2].
Engineered tier (USD 800–several thousand): AC-motor clamping units like the Römheld D8.013 with selectable 160/250/500 bar operating pressure, 750 W or 1.1 kW motor options, 0.9/2.5/4.5 L/min flow variants, and an 11 L tank — typically specified into press-fixture, workholding, and machine-tool cells with two-hand safety control [S3]. Specialty tier (USD several thousand and up): aviation hydraulic ground power units built around 3000 psi aircraft-class systems, distributed for mainline/narrow/wide-body servicing and tied to TEST-FUCHS-type ground support specifications [S8].
Comparison: combustion engine versus AC motor at a glance
Three decision criteria differentiate the two families: pressure ceiling, installation footprint, and operating cost. Combustion-engine units such as the MGHT 2A and GHTI 2S reach 700 bar (10,153 psi) from a 1–3 L tank, weigh around 27 kg, and run where mains power is absent [S1][S2]. AC-motor units top out at 500 bar (7,252 psi) on the D8.013, ship a larger 11 L reservoir, and need a 3 m control-cable run plus a 300×400×155 mm control box for EN ISO 13851 logic [S3].
On cost of ownership, combustion packs burn petrol and need pull-rope starting plus routine engine servicing, while AC-motor clamping cells consume plant power, run quieter indoors, and integrate with machine safety PLCs but require panel space for the control box [S1][S2][S3]. For field erection, rescue tooling, and mobile stressing, the combustion-engine tier wins on pressure and autonomy; for stationary workholding and press fixtures, the AC-motor tier wins on repeatability, noise, and safety-bus integration.
Total cost of ownership beyond the line item
Purchase price covers only the pump, motor, tank, and valve block. Installation costs include mounting frames, two-hand console wiring, hydraulic hose runs, and oil fill — the D8.013 ships with a mounting frame that carries the control box and connects via a 3 m cable to the two-hand console [S3]. Maintenance costs scale with oil-change intervals, filter replacement, and seal kits; a 700 bar two-stage pump with separate pressure-relief valves per stage typically costs more in spares than a single-stage 250 bar clamping pump.
Energy cost is a hidden driver: a 750 W AC motor running an 8-hour shift pulls 6 kWh/shift, while a 98 cc petrol engine on the MGHT 2A burns roughly 0.5–1 L/h under intermittent load [S1][S3]. Downtime cost is the real penalty — a noise/safety-noncompliant pack pulled from a European line, or a 700 bar pack that fails pressure-test certification, will cost more in lost production than the price gap between tiers. For deeper spec work on duty-cycle matching, the Hydraulic Power Unit Selection: Pressure, Flow, and Duty-Cycle Criteria page lines out the engineering checklist.
Standards and sourcing signals to verify before purchase
EN ISO 13851 governs the two-hand control principle used on the D8.013 clamping console, with a 0.5 second simultaneity requirement between the two mushroom pushbuttons [S3]. Aviation HPUs follow TEST-FUCHS-type ground support specifications and serve 3000 psi mainline/narrow/wide-body aircraft systems, which sets a different documentation and calibration regime than industrial packs [S8].
For sourcing, Chinese suppliers on Made-in-China list MOQs of 1 piece across both manual/electric and AC-motor units at USD 100 and USD 1,000 price points, with L/C, T/T, D/P, and Western Union payment terms and Shanghai as the dominant port [S5][S10]. Stationary HPU sourcing spans 34 manufacturers and 74 catalog products on the major B2B portals, including Bosch Rexroth, Continental Hydraulics, ATOS, and Berg & Co. Spanntechnik, so RFQs should pull at least three comparable data sheets before committing [S4]. For engineers cross-referencing pump-side spec, the Centrifugal Pump Selection Criteria page covers the adjacent pump selection logic, and the Hydraulic Power Unit vs Hydraulic Pump page clarifies where a packaged HPU ends and a bare pump begins.
Track the 5.9% CAGR trajectory of the hydraulic power unit market against your own installed-base growth, using the USD 12.4 billion 2022 baseline reported in [S7]. Cross-check the indicative USD 100 / USD 1,000 anchors against fresh RFQs on the hydraulic power unit category page, and treat any quote more than 30% below the band as a flag for missing certification, undersized reservoir, or single-stage pump masquerading as two-stage.
