Project Introduction

A mining company in Jilin has purchased an MD200-50X7P multistage pump.

This medium-sized metal mine in Jilin has been in operation for many years, with underground mining reaching depths of over 300 meters, and its mine water consistently contains fine sand. Previously… Old-style multistage pump The balance disc is highly susceptible to wear, requiring monthly shutdowns for disassembly and maintenance. During the rainy season, when inflow rates surge, inadequate drainage can directly disrupt mining operations, keeping operating and maintenance costs persistently high. After comparing feedback from peers, the mine opted for a custom drainage solution tailored by us. Our technicians conducted an on-site assessment: the mine’s typical inflow is 200 m³/h, with total head losses in the piping system amounting to 350 meters; the conveyed fluid contains trace amounts of silt, necessitating equipment that is wear‑resistant, requires minimal maintenance, and can operate continuously over extended periods. Based on these operating conditions, we selected the MD200‑50X7P self‑balancing multistage pump.

  This Level 7 model Self-balancing pump Rated flow: 200 m³/h; head: 350 m. Equipped with a symmetrical impeller that counteracts axial thrust, eliminating the need for frequent replacement of the balance disc. The impeller and pump casing are made of high-chromium wear-resistant material, significantly enhancing resistance to sand and sediment erosion, and are paired with an explosion-proof motor suitable for underground applications.
