Putzmeister — PHS Magnum’s core specialism
PHS Magnum has been servicing Putzmeister concrete pumps for over 30 years. We know every component intimately — from the simplest BSF trailer pump to the latest M42-5 with its 42-metre boom and Ergonic system.
Putzmeister is the most widely used concrete pump brand in Poland — the majority of concrete contractors run these machines. That makes Putzmeister a natural focus for specialist service providers, and it means parts availability is the best in the market — making Putzmeister the most economical long-term choice for owners.
Models we service
M-Series truck-mounted boom pumps
- M24-4 (24 m reach, smallest in the boom range) — compact, popular in residential construction
- M28-4 (28 m) — standard segment
- M31-5 (31 m) — versatile all-rounder
- M36-4, M38-5 (36–38 m) — larger commercial projects
- M42-5, M46-5, M47-5 (42–47 m) — major commercial buildings, bridges
M-Series designation: the number is the boom’s vertical reach in metres; the digit after the hyphen is the number of boom sections. Engine: Mercedes-Benz or Cummins diesel (depending on year of manufacture). Multi-section boom in hardened steel, hydraulic outriggers, integral water tank.
Trailer pumps (stationary, chassis-mounted)
- BSF series — the most common, high-pressure output (up to 380 bar), flow rates up to 200 m³/h
- THOM, THO — older generations, still widely in service
- BS, BSA — compact units for tunnelling applications
No boom — concrete is pumped through laid pipe or hose to the pour location. Requires a placing boom or an operator positioned at the delivery end.
Pumi truck mixer pumps
- Pumi 24 (24 m reach + integral drum mixer) — smallest in the Pumi range
- Pumi 28, 30, 36 — larger versions
A hybrid combining a concrete mixer and a boom pump on a single chassis. Service complexity: the drum mixer, pump unit and boom must all be maintained together on the same vehicle.
Putzmeister service specifics
S-valve — the critical component
Putzmeister uses its own proprietary S-valve (named for its S-shaped profile). Advantages: efficient flow geometry, long service life, and the possibility of reconditioning by hard-facing. Disadvantages: high replacement cost on larger models (quoted individually), and precision welding required during repair.
Typical S-valve failure modes:
- Cutting-edge wear (6–15 mm material loss) — requires hard-facing or replacement
- Body cracking — replacement only; repair is not viable
- Internal corrosion in idle pumps (hardened concrete residue inside)
PHS Magnum procedure:
- Diagnostics — calliper measurement of wear, visual inspection of the body
- Decision: HB600 hard-facing (wear under 8 mm) or replacement
- Hard-facing — 1–2 days: valve removal, cleaning, HB600 build-up welding, grinding, polishing of working surfaces, reassembly
- Pressure test to 380 bar
- Trial run with test concrete on the yard
Ergonic system — OEM diagnostics
Ergonic (current generation) — full CAN-bus with sensors covering: hydraulic pressure, concrete pressure, oil temperature, cyclic output, boom position and joint angles.
Without an Ergonic tester, repair of any post-2010 Putzmeister M-Series is effectively impossible in terms of full diagnostics. PHS Magnum holds an original OEM tester.
Concrete cylinders — reconditioning
Two concrete cylinders (A and B, pumping alternately) with hardened steel liners. Wear manifests as hydraulic oil leaking into the concrete, or — significantly worse — concrete entering the hydraulic circuit.
Reconditioning procedure:
- Cylinder removal
- Wear measurement (internal diameter micrometer)
- Honing to the next oversize
- Fitting rubber pistons of the correct oversize
- Pressure and operational testing
Where cylinders are beyond the third oversize, replacement is the correct course of action.
Most frequent interventions 2024–2026
Workshop statistics from our facility (past 24 months):
| Intervention type | Frequency |
|---|---|
| Rubber piston replacement | 35% |
| Oil and filter change | 20% |
| Ergonic diagnostics and fault code clearing | 15% |
| S-valve hard-facing | 8% |
| Cylinder reconditioning | 6% |
| Hydraulic repair (valves, hoses) | 8% |
| Boom repair (welding, lubrication) | 5% |
| Other (electrical, cooling water) | 3% |
Mobile Putzmeister service
A mobile technician with an Ergonic tester travels to:
- Poland — nationwide; most frequently Silesia, Lesser Poland, Lower Silesia (200–400 km from base)
- Germany — border region, up to 100–200 km
- Czech Republic — northern areas (up to 250 km)
Work carried out on site: Ergonic fault diagnostics and clearing, piston replacement, oil change, electrical repairs, minor hydraulic servicing. Workshop-only work: cylinder reconditioning, S-valve repair, boom welding, bodywork, TDT inspection.
