Concrete Pumps & Placing Booms
Hydraulic Pumping
Selection depends on three numbers — peak m³/h required, horizontal distance, and vertical height — plus an honest look at the mix: aggregate shape, fines content and slump determine whether a given pipeline length is achievable at all.
Concrete has to arrive at the formwork continuously and without segregation. That is the entire purpose of this product family: Hydraulic Pumping equipment takes plastic concrete from a truck or mixer and delivers it horizontally along a pipeline or vertically through a placed boom, at a rate the finishing crew can absorb.
Choosing a Hydraulic Pumping is rarely decided by the price tag alone. Downtime, concrete quality consistency, fuel consumption per cubic metre and the availability of wear parts across a five-year operating window matter far more to the final cost per tonne or per cubic metre produced.
Key Advantages of Hydraulic Pumping
Wash-out systems included
Integrated water tank, high-pressure pump and cleaning accessories reduce end-of-shift time.
Continuous placement
Steady flow keeps cold joints out of slabs and eliminates the double-handling cost of crane-and-skip methods.
Diesel and electric variants
Choose engine power for remote sites or electric motors for tunnels and urban night work.
S-tube valve reliability
Hardened wear plates and cutting rings provide extended service intervals under abrasive mixes.
Safety built into the controls
Outrigger interlocks, boom angle limits and emergency stop circuits protect both crew and structure.
Boom reach without a crane
Independent placing puts concrete precisely where the crew is working without occupying lifting capacity.

Typical Applications
The applications below reflect the situations in which HAMAC customers most commonly deploy it.
Dams and hydropower
Mass pours with sustained continuous output
Bridges and viaducts
Long horizontal pumping runs to piers and deck segments
Large industrial slabs
Spider booms covering wide floor areas without repositioning
Precast and yard casting
Fixed placing booms serving repetitive casting beds
High-rise buildings
Vertical concrete delivery exceeding 100 m using riser pipelines or self-climbing booms
From Enquiry to Commissioning
Six defined stages, each with named deliverables, so nothing is left to interpretation.
Requirement study
We start with your mix design, hourly output target, aggregate size, jobsite power supply and site layout — not with a catalogue page.
Scheme design
Our engineering team issues a layout drawing, foundation loads, power requirement and an equipment list matched to the target output.
Quotation & contract
A fixed specification quotation with clear technical annexes protects both sides; no vague "standard configuration" wording.
Production & inspection
Weekly production photos, welding and pressure test records, plus third-party inspection if your project requires it.
Delivery & installation
Container or break-bulk shipment, then on-site supervision of assembly, alignment, calibration and dry-run.
After-sales
Remote diagnostics by video call, spare parts dispatch within 48 hours for stocked items, and periodic return visits.
Frequently Asked Questions about Hydraulic Pumping
Do I need a special mix design for pumping?
Yes, a pumpable mix: continuous grading, sufficient fines (roughly 350-400 kg/m³ below 0.25 mm), and no gap-graded coarse aggregate.
What is the expected service life of wear parts?
Delivery cylinders 40,000-80,000 m³, cutting ring and wear plate 15,000-30,000 m³ depending on aggregate abrasiveness.
How tall can it pump?
Vertical reaches of 100-150 m are routine with correctly designed pipelines and adequate concrete pressure.
Can the machine handle low-slump concrete?
Most units are optimised for 120-200 mm slump; below that, pressure requirements rise sharply and output falls.
How do I prevent pipeline blockages?
Keep slump at 120-180 mm, maintain adequate fines, prime the line with mortar before each pour and avoid long idle periods.
