JH-20 Electric Concrete Pump Description

The JH-20 electric mini concrete pump is a compact, site-mobile concrete pumping machine developed for conveying fine aggregate concrete in building and civil engineering projects. Powered by a 22 kW electric motor, this hydraulic concrete pump provides a theoretical conveying capacity of up to 15 m³/h and a maximum hydraulic system pressure of 18 MPa, supporting vertical delivery distances of up to 40 m and horizontal delivery distances of up to 80 m under suitable operating conditions. The machine can handle aggregates measuring up to 20 mm and works with 80 mm or 100 mm conveying pipes, making it suitable for secondary structural columns, ring beams, floor slabs, foundations, renovation projects and restricted-access construction sites. Compared with a diesel concrete pump, the electric drive produces no engine exhaust at the machine, requires less routine engine maintenance and is well suited to indoor or emissions-sensitive projects where a compatible 380 V power supply is available. Its compact frame, straightforward control system and accessible service points make the JH-20 a practical small concrete pump for contractors, rental companies and construction equipment distributors across Europe.

Technical Specifications

Actual pumping output and conveying distance may vary according to concrete mix design, aggregate grading, slump, pipe diameter, pipeline arrangement and vertical lifting height.

Key Advantages of the JH-20 Electric Mini Concrete Pump

• Efficient 22 kW electric drive:                Provides stable power for continuous fine concrete pumping while reducing routine engine maintenance.

• High-pressure hydraulic system:                The 18 MPa hydraulic system supports reliable concrete delivery through vertical and horizontal pipelines.

• Handles aggregates up to 20 mm:                Suitable for correctly proportioned fine aggregate concrete used in structural and general construction work.

• Extended conveying capability:                Delivers concrete up to 40 m vertically and 80 m horizontally under suitable site and mix conditions.

• Compact and site-mobile design:                Easier to position in restricted construction areas where larger concrete pumping equipment cannot operate efficiently.

• 80 mm and 100 mm pipe compatibility:                Allows the delivery pipeline to be selected according to the concrete mixture and project requirements.

• No engine exhaust at the machine:                The electric concrete pump is suitable for enclosed, urban and emissions-sensitive construction environments with an appropriate electrical supply.

• Convenient operation and maintenance:                A practical control layout and accessible components support daily inspection, cleaning and servicing.

Applications of the JH-20 Fine Concrete Pump

The JH-20 small electric concrete pump is suitable for a wide range of residential, commercial and civil engineering applications.

• Secondary structural column pouring

• Ring beam and structural beam filling

• Fine aggregate concrete conveying

• Residential and commercial building construction

• Floor slab and foundation concrete placement

• Retaining walls and small civil engineering projects

• Concrete placement on upper floors

• Renovation and building extension projects

• Restricted-access and narrow construction sites

• Indoor projects with suitable ventilation and electrical supply

Recommended Concrete and Operating Conditions

For stable pumping performance, the concrete mixture should have suitable workability, consistent aggregate grading and a maximum aggregate size not exceeding 20 mm. The delivery pipeline should be arranged with as few sharp bends as possible and securely supported throughout the pumping route. Before operation, the pipeline should be inspected and correctly primed. After use, the hopper, pumping system and delivery pipes must be cleaned promptly to help prevent hardened concrete and pipeline blockage.

Frequently Asked Questions

What materials can the JH-20 electric concrete pump convey?

The JH-20 is designed primarily for pumpable fine aggregate concrete. The mixture must have suitable workability and aggregate grading. Customers should provide the concrete specification before ordering so that ACE Machinery can confirm compatibility.

What is the maximum aggregate size for this concrete pump?

The maximum allowable aggregate size is 20 mm. Oversized or poorly graded aggregate may increase the risk of pipeline blockage and premature wear.

What is the pumping capacity of the JH-20 electric model?

Its theoretical conveying capacity is up to 15 m³/h. Actual site output depends on the concrete mixture, pipeline diameter, conveying distance, lifting height and operating conditions.

How far can the JH-20 pump concrete?

Under suitable operating conditions, the maximum reference conveying distance is up to 40 m vertically or 80 m horizontally. Complicated pipe layouts and multiple bends can reduce the effective distance.

What electrical supply does the JH-20 require?

The standard electric model is equipped with a 22 kW motor and a 380 V power supply. Buyers should confirm the local voltage, frequency and phase before ordering, especially for European construction sites.

Is the JH-20 suitable for use in Europe?

The machine can be configured for suitable construction applications in European markets. The required electrical specification and available conformity documents should be confirmed according to the destination country before placing an order.

Does this machine include an integrated concrete mixer?

No. The JH-20 is a concrete conveying pump rather than a concrete mixer pump. It should be supplied with correctly mixed concrete from a separate mixer, batching system or ready-mix concrete source.

What is the difference between the electric and diesel JH-20 models?

The electric model is suitable for sites with a stable electrical supply and produces no diesel engine exhaust at the machine. The diesel version provides greater independence on remote sites where electricity is unavailable or unreliable.

How can pipeline blockage be prevented?

Use a suitable pumpable concrete mix, keep the aggregate within the specified size, prime the pipeline before pumping, avoid unnecessary sharp bends and clean the entire pumping system immediately after operation.

Is the JH-20 a portable concrete pump?

The JH-20 has a compact, site-mobile design compared with large stationary or truck-mounted pumps. Because the machine weighs approximately 1,100 kg, suitable lifting or transport equipment should be used when moving it between sites.

What inspection documents are provided?

A machinery test report and video outgoing inspection can be provided. Please contact ACE Machinery to confirm any additional documentation required for your destination market.

What warranty is provided for the JH-20 concrete pump?

The standard warranty period is one year. Operating guidance, maintenance assistance and spare parts support are also available from ACE Machinery.
