What Is the Size of a Small Concrete Mixture Pump?

Small concrete mixture pumps are essential for construction projects where space is limited, mobility is crucial, and large-scale pumping equipment is impractical. These compact machines combine concrete mixing and pumping in a single unit, making them ideal for residential construction, landscaping, and small-scale commercial jobs.

This guide explores the size specifications of small concrete mixture pumps, including dimensions, weight, output capacity, and how their compact design compares to larger models. We’ll also discuss key factors influencing size selection and provide real-world application examples.

Defining a Small Concrete Mixture Pump

A small concrete mixture pump typically refers to a portable machine that:

Mixes concrete (either manually or with an onboard mixer).

Pumps concrete through a hose or pipeline.

Weighs under 3,000 kg (6,600 lbs).

Fits in tight spaces (narrow alleys, basements, backyards).

These pumps are commonly used for:

✔ Residential slabs & foundations

✔ Swimming pool construction

✔ Garden pathways & decorative concrete

✔ Repair work & grout injection

Standard Size Specifications

The size of a small concrete mixture pump varies by model, but most fall within these ranges:

A. Physical Dimensions

| Component | Size Range (Small Pumps) | Comparison to Large Pumps |

|-----------------------|----------------------------------|-----------------------------|

| Length | 2.5m – 4m (8.2ft – 13ft) | Large pumps: 6m+ (20ft+) |

| Width | 1m – 1.5m (3.3ft – 5ft) | Large pumps: 2.5m+ (8ft+) |

| Height | 1.5m – 2m (5ft – 6.5ft) | Large pumps: 3m+ (10ft+) |

| Hose Length | 10m – 50m (33ft – 165ft) | Large pumps: 100m+ (330ft+) |

Example Models:

Mini Electric Concrete Pump: 2.8m × 1.2m × 1.6m

Diesel Mixer-Pump Combo: 3.5m × 1.4m × 1.8m

B. Weight & Portability

Weight: 500kg – 3,000kg (1,100 – 6,600 lbs).

Mobility:

Some models have wheels or trailers for towing.

Others are skid-mounted (require forklift loading).

C. Output Capacity

Concrete Output: 10 – 30 m³/h (small concrete pumps) vs. 60 – 150 m³/h (large boom pumps).

Mixer Capacity: 200L – 500L per batch.

Key Factors Influencing Size

A. Power Source

Electric Pumps: Smaller, lighter (best for indoor use).

Diesel Pumps: Bulkier but more powerful (for remote sites).

B. Pumping Mechanism

Piston Pumps: Compact but higher pressure.

Screw Pumps (Auger): Wider due to mixing chamber.

C. Hose Diameter

Small pumps: 2" – 4" hose (narrower = more compact).

Large pumps: 5" – 8" hose.

Advantages of Small Size

✔ Fits in confined spaces (backyards, basements).

✔ Easier transport (fits on a small trailer).

✔ Lower fuel/power consumption.

✔ Faster setup time (under 30 minutes).

Limitations

✖ Lower output than large pumps.

✖ Shorter reach (hose length limits placement).

✖ Not ideal for high-rise projects.

How to Choose the Right Size

Step 1: Assess Project Needs

Small slabs? → 10m³/h pump.

Multi-story? → High-pressure mini pump.

Step 2: Check Access Routes

Narrow gates? → <1.2m width required.

Soft ground? → Lightweight (<1,500kg) preferred.

Step 3: Compare Fuel Efficiency

Electric: 5-10kW vs. Diesel: 15-30HP.

Real-World Applications

Home Foundations: 3m × 1m mini pump.

Tunnel Grouting: Ultra-compact 2.5m pump.

Small concrete mixture pumps range from 2.5m–4m long, weigh 500–3,000kg, and output 10–30 m³/h. Their compact size makes them perfect for residential and light commercial work where large pumps can’t operate.

Final Tip: Always measure job site access points before selecting a pump size. For tight spaces, consider mini electric models under 1.5m wide.

By matching pump size to project needs, contractors maximize efficiency while minimizing logistical headaches.
