Why Choose YG Construction Concrete Pump?
S-tube distribution valve design, compatible with various aggregates
The YG series is fitted with an S-tube distribution valve featuring gentle diameter transition and smooth flow channels. It can convey standard concrete and well handle special materials such as small-aggregate concrete, fine stone mortar, lightweight foamed cement for floor heating insulation. Compared with gate valves, the S-tube valve brings lower pressure loss and shows obvious advantages for long-distance pumping in high-rise buildings. It maintains stable discharging even with aggregates ranging from 0~5 cm, effectively lowering pipe blockage risks.
Variable displacement piston main pump, energy efficient
The main pump uses a variable displacement piston pump. It achieves higher volumetric efficiency and stronger pressure output than traditional gear pumps, with less temperature rise during long continuous operation. With the same power input, the YG diesel concrete pump can provide higher theoretical pumping pressure and steady flow, while consuming less fuel or electricity to help contractors save energy costs. It is ideal for large projects with tight schedules and high concrete demand.
Independent 3-circuit hydraulic system, leading reliability in the industry
YG’s hydraulic system adopts independent 3-circuit control: pumping circuit, reversing circuit and mixing circuit operate separately without mutual interference. If one circuit fails, others can still function normally, significantly reducing full-machine downtime. This design also improves system heat dissipation and simplifies maintenance, extending the service life of hydraulic components and ensuring stable heavy-duty operation.
Hard alloy key wear components for much longer service life
Spectacle plates and cutting rings are the most vulnerable parts of a diesel concrete pump. YG applies high-hardness hard alloy and special processing technology to these core parts, delivering far better wear resistance than ordinary cast iron or steel parts. In practical use, their service life can be extended by 30%~50%, lowering replacement frequency and spare part expenses. For long-term construction projects, this advantage directly cuts overall equipment operation and maintenance costs.
Dual-cylinder piston pumping mechanism: stable flow & low impact
YG equips a dual-cylinder piston pumping system. Two main cylinders push concrete alternately with smooth stroke switching and excellent continuous pumping performance, avoiding obvious pulsation found on single-cylinder pumps. This structure improves conveying efficiency and reduces pressure fluctuation inside pipelines, protecting pipe joints and elbows. It is well suited for precision projects such as bridges and tunnels requiring stable pumping performance.


Main Components of YG Construction Concrete Pump
A complete construction concrete pump consists of the pump main unit and delivery pipes. The YG series integrates three core systems on this basis:
- Intelligent Control System: Supports high/low pressure switching. The exclusive valve switching unit enables two pumping modes: high pressure with small displacement and low pressure with large displacement. It adopts stepless variable regulation for real-time output adjustment. The fully automatic centralized lubrication system protects moving components, and the PLC controller ensures simple and reliable electric control.
- Hydraulic System: Open-type dual-pump dual-circuit design; pumping circuit and reversing oil circuit work independently for simplicity and reliability. The bypass cooling plus forced air cooling system effectively controls hydraulic oil temperature.
- Pumping System: Large-inclination hopper boosts feeding efficiency. The S-tube valve has a smooth transition for fluent material delivery. Core parts adopt international brands including Kawasaki (Japan), Parker (USA), Siemens and Schneider (Germany).
How to Select the Suitable Concrete Transfer Pump?
Three key factors should be considered during model selection:
- Delivery height and distance: Select the discharge pressure based on required vertical pumping height and horizontal conveying distance. The Model 30 construction concrete pump reaches up to 60 m vertical and 150 m horizontal; Model 50 supports long-distance delivery up to 150 m vertical and 500 m horizontal.
- Required output capacity: Match the production rate to your mixer feeding capacity. Model 20 (8-12 m³/h) fits small-scale floor heating and mortar filling. Model 60 (55-60 m³/h) works for large tunnel and bridge construction.
- Aggregate size limit: S-valve has relatively strict aggregate requirements yet low pressure loss, perfect for long-distance pumping in high-rises. YG series handles aggregates up to 0-5 cm and works well with fine aggregate concrete and mortar.


How to Prevent and Clear Blockages on a Construction Concrete Pump?
Pipe blockage is the most common fault during concrete pumping. Follow these tips for effective prevention:
Preventive Measures
Keep a close watch on the pumping pressure gauge during operation. Start pumping at low speed and increase speed only after stable operation. Do not let material level in the hopper drop below the mixing shaft to avoid air intake. For high-rise pumping, the horizontal pipeline length should be no less than 15% of vertical pipeline length. Run the pump every 5–10 minutes during shutdowns to prevent concrete initial setting.
Troubleshooting Methods
Once a sudden pressure surge appears, activate reverse pumping for 2–3 strokes, then switch back to forward pumping. If ineffective, tap the blocked section with a wooden mallet while alternating forward and reverse pumping. Dismantle and clean the pipeline if blockage still cannot be cleared.
