**Small Fine Concrete Transfer Pumps – Product Introduction**
The HW high-floor cement mortar pump is a compact and efficient fluid conveying system designed for various construction applications. It is widely used in high-rise building projects for wet-mixed mortar pumping and wall plastering, as well as for support lining in ground heating systems, tunnels, and mining operations.
This machine can efficiently pump fine aggregate concrete with a maximum particle size of less than 25mm, offering a cost-effective solution for construction projects. Its design includes an S-tube distributor valve that allows it to handle larger aggregates, making it ideal for different types of concrete delivery.
The hydraulic-driven mixing device ensures secondary mixing, which improves the flowability and pumpability of the material. The wear-resistant glass plate and cutting ring are made with hard alloy inlay technology, ensuring long service life and durability.
The hydraulic system features independent three-circuit electro-hydraulic control, providing high reliability and stability. The electrical system includes a return pressure control function, which helps prevent pipe blockages and ensures smooth operation.
With its sleek design and lightweight structure, this pump is easy to transport and install. When used in conjunction with batching mixing equipment, it enables continuous pumping operations, significantly improving the construction schedule.
