Mining Pumps

Mining pumps handle core functions in underground mining operations. They supply emulsion to hydraulic roof supports, power dust suppression at shearers and plow systems, and maintain cooling for drive motors. As Triplex and Quintuplex plunger pumps and as pump skids, KAMAT supplies mining pumps with discharge pressures up to 4,000 bar (58,000 psi) and drive power up to 3,000 kW (4,023 hp).

As mining depth increases and longwall faces extend, rock pressure rises and the forces acting on hydraulic roof supports grow with it. At the same time, faster extraction speeds require quicker shield movement. KAMJET pump units deliver the required emulsion volume reliably under these changing load conditions, backed by decades of experience in mining regions including the United States, Australia, Russia, and China.

Mining places demands on pump technology that stem directly from the geological and operational conditions found underground. Two factors are decisive: rock pressure that rises with mining depth, and the need for uninterrupted continuous operation.

Pressure increase from growing mining depth and longwall length

As mining depth increases and longwall faces grow longer, rock pressure rises. The forces transmitted into the hydraulic roof supports increase accordingly, and hydraulic pressures and shield cylinder diameters grow along with them. At the same time, faster extraction machine speeds demand quicker shield movement. High-pressure pumps must deliver this rising discharge pressure and increasing flow volume without any loss of performance.

Requirements for availability and continuous operation

Hydraulic stations in mining run around the clock, and any failure interrupts the entire extraction process. Pressure fluctuations caused by long supply lines or varying operating speeds must be compensated for without affecting system availability. Low speeds during partial-load operation must not shorten component service life either, which calls for lubrication and gear systems designed specifically for this purpose.

KAMAT pump units are designed for a range of applications, from large hydraulic stations to dust suppression spray systems, with power ratings up to 800 kW (1,073 hp) and discharge pressures up to 4,000 bar (58,000 psi) in continuous operation.

Hydraulic roof supports

For roof support in the longwall face, KAMAT Triplex and Quintuplex plunger pumps supply the hydraulic emulsion volume that high extraction speeds and rising rock pressure require, with discharge pressures up to 4,000 bar (58,000 psi) in continuous operation. Speed control on the pumps reliably compensates for pressure fluctuations caused by varying line lengths or changing operating speeds.

Dust suppression and spray systems

At shearers, plow systems, and in general spray applications, KAMAT pumps provide constant pressure and flow rates. This reduces dust exposure in the longwall face and supports workplace safety underground.

Central hydraulic supply for mines

For supplying hydraulic fluid to entire mines or individual longwall faces, KAMAT delivers preconfigured pump skids, installation-ready and matched to the required flow rate, with discharge pressures up to 4,000 bar (58,000 psi). This reduces engineering effort during system planning and shortens on-site commissioning time.

KAMAT pumps offer an exceptionally wide control range of 90 percent, delivering between 100 and 10 percent of nominal flow volume. This engineering achievement avoids unnecessary wear, since the valves no longer need to switch constantly. Purpose-built frequency converter systems control this wide range with fine precision, enabling precisely controlled pump operation. This makes it simple and reliable to compensate for pressure fluctuations caused by supply line length or varying speeds in mining operations. Correspondingly designed lubrication also secures reliable operation at low speeds.

A typical mining station has three high-pressure pumps. With frequency converter control, the entire pump system can be regulated through a single frequency-controlled master pump. The other two pumps switch on or off only as needed, while the master pump handles the remaining flow volume. As a result, only one frequency converter is required per station, which lowers investment costs accordingly. All KAMAT pump models can also be operated as vertical pumps, providing additional flexibility for spatial arrangement.

KAMAT mining pumps are designed for the demands of underground mining and deliver high performance with high availability. They handle the increased rock pressure that results from deeper and longer mine workings, and support efficient hydraulic shield operation as well as dust control.

• Discharge pressure up to 4,000 bar (58,000 psi): The entire portfolio, from Triplex and Quintuplex plunger pumps to KAMJET high-pressure units, covers pressure ranges that leave reserve capacity for roof support and spray applications even under rising rock pressure.
• Durable construction: Gearboxes designed for low-speed operation increase durability and robustness, even under demanding underground conditions.
• Modular system design: Shared components across multiple product lines simplify spare parts management, shorten delivery times, and reduce service effort, a direct advantage during downtime underground.
• Certifications: CE, API 674, and ATEX are available for KAMAT pumps and support use in regulated mining environments.
• Wide control range: KAMAT pumps achieve a control range of 90 percent, from 100 down to 10 percent of nominal flow volume. This enables wear-free pressure regulation, since the valves no longer need to switch constantly, an engineering achievement that significantly increases equipment protection and service life.
