Construction Double-Diaphram Plunger Pump
Our Construction Double-Diaphram Plunger Pump moves thick mixes of solids and liquid under high pressure. Per the maker's data, it can transfer a mix that is about 50% solids, with particles up to 1.5 mm. We build it in China and ship it to contractors and importers who need a pump that handles grit without fast wear.
What the Double-Diaphram Plunger Pump is for
In this design, a plunger drives a diaphragm that pushes the mix, so the plunger itself does not touch the abrasive slurry. With two sides working in turn, the flow is steadier than from a single unit. That suits filter press feeding, grout and slurry transfer, and similar site work.
The maker lists a pressure range of 0-80 kg and a flow of 1-15 tons per hour. If your duty is lighter, compare our single-diaphram plunger pump, which is the simpler option in the same family.
Typical build and controls
The specification table below holds the full data. Values marked as typical describe what this type of pump usually has, and we confirm them for your order:
- Drive and controls: usually hydraulically driven and operator controlled
- Pump unit: a twin-cylinder diaphragm and plunger pumping unit
- Build: steel pump cylinders with wear-resistant plunger seals
- Class range: typically 60-180 m³/h output at 8-24 MPa pressure, though this model's own figures above come first
Points to confirm before you order
We ask each buyer for a few facts before we quote, since slurry pumps are sized to the mix:
- The solids share and the largest particle size you will pump
- The pressure and flow you need at the delivery point
- Your local voltage and frequency for the drive
- Whether the order is for a government tender, and its deadline
Site teams often check pump installs against general plant safety rules. The OSHA construction safety site and the EU Machinery Regulation and CE marking guidance are good places to start.
Export supply of the Double-Diaphram Plunger Pump
We supply single units, bulk orders and tender lots to Nigeria, Kenya, Ghana and other markets. Each pump is crated for sea freight and ships with the commercial invoice, packing list, certificate of origin and bill of lading. The certifications and compliance page sets out which extra papers can be requested.
Send us your slurry details and port, and we will confirm fit, lead time and a quote. You can also see our wider range of Construction Machinery.
