Frequently Asked Questions

What are the primary differences between the BW-150 and BW-250 models?

The BW-150 operates with a stroke length of 70mm, 7.5 KW input power, and reaches displacements up to 150 L/min. The BW-250 offers a longer 100mm stroke, requires 15 KW input power, and delivers larger displacement configurations (up to 250 L/min or 166 L/min depending on the liner size).

Which BW pump model is suitable for deepest diamond core drilling?

The BW-320 is the most capable model for ultra-deep holes, supporting diamond core drilling depths up to 3000 meters and conventional core drilling up to 2000 meters, powered by a 30 KW system.

How does liner diameter affect pump pressure and displacement?

A larger liner diameter increases displacement (flow rate) but yields lower maximum pressures. For example, in the BW-250, an 80mm liner delivers up to 250 L/min flow at max 6.0 Mpa, while a smaller 65mm liner yields up to 166 L/min flow but reaches higher pressures up to 7.0 Mpa.

What makes the BW-300/12 different from the other models?

Unlike the single-acting design of the BW-150, 250, and 320, the BW-300/12 features a double-acting triplex-piston design. It supports high-intensity directional drilling, uses a 45 KW input, and achieves a maximum pressure of 12.0 Mpa.

What power options and configurations are available for the mass groups?

The equipment weights vary depending on configuration: the BW-150 group weighs 516 kg (with an electric motor), and the BW-320 group weighs 1000 kg (equipped with a diesel engine), accommodating diverse job site power requirements.
