Pneumatic Mortar Conveyor Screed Pump

Our HWDPX series pneumatic mortar conveyor screed pumps all feature a motor-driven mixing mechanism combined with an external on-site air compressor for air supply. By utilising the existing compressed air system at the construction site, they offer lower acquisition costs and can efficiently convey dry materials, semi-dry mortar, and low-moisture wet mixes. They are widely used in self-leveling floor screeds, building floor levelling, and the construction of refractory castables for metallurgical ladles.
 

HWDPX200: Equipped with an 11kW motor and a 200L pressure tank, it requires an air compressor with a minimum air delivery rate of ≥4m³/min. The standard aggregate size is ≤16mm, but this can be increased to 32mm by replacing the large-diameter delivery hose and discharge riser. Designed primarily for small to medium-sized domestic flooring and sporadic repair works, the pneumatic mortar conveyor screed pump is simple to operate, easy to transport, and has extremely low maintenance costs, making it the economical workhorse model for small-scale construction projects.
 

HWDPX500: 22 kW motor, 500 L pressure tank, streamlined design with no unnecessary components; requires an air compressor with a minimum air delivery rate of ≥5 m³/min; standard aggregate size ≤32 mm, which can be reduced to 25 mm with a simple modification; suitable for a full range of materials including dry sand, masonry mortar, cement-based/gypsum-based self-levelling compounds, fine aggregate concrete, crushed stone, backfill soil, and roof insulation aggregates. It can handle dry materials and semi-dry mixtures that cannot be pumped by screw or piston pumps, and is frequently used for large-scale floor construction and the conveyance of sand and gravel for site backfilling. In addition to standard construction mortar and fine aggregate concrete, this pneumatic concrete mix conveyor is also suitable for the conveyance of refractory castables for ladles, tundishes, and blast furnace chutes in the metallurgical industry.
 

HWPXT200-D/A: Equipped with a Cummins engine and air compressor, this unit features an integrated trailer-mounted design that eliminates the need for an external air compressor. This pneumatic mortar conveyor screed pump can be put into operation immediately at remote construction sites without a fixed air supply. As a best-selling workhorse model in the construction industry for foundation pouring, large-area floor concrete, and fine aggregate concrete sub-base works, it has been specifically developed for long-distance pumping in high-rise buildings.
