High performance pumping stations for pumping water out of quarries

Project details

The client had a task to pump out particularly polluted water, with the content of boulders up to 5 cm in diameter, flowing at a high speed - up to 50 thousand cubic meters per day! You don't encounter such conditions every day, and we started to work on the project with great interest. We chose one of the most unpretentious, powerful and reliable components - American Cornell pumps and Korean Doosan motors. Cornell pumps have undeniable advantages for working in such severe conditions: the ability to operate for a long time in dry running mode and special seals that allow you to pump contaminated fluid without barrier fluid supply to the pump.

One of the interesting design features is as follows

• Hood with noise reduction elements (modern materials are used for noise suppression, and the hood design diverts the noise flow from the fan up, which does not cause inconvenience to operators);
  
• To work in severe conditions of the North, the "Northern package" is used, which includes not only engine heating systems , but also heating of some pump elements;
• A particularly strong frame structure that allows for the upper overloading of stations with a total weight of 9 tons.
  Support structures have a 10-fold margin of safety.
  Special design of skis in which our designers have found the most optimal balance between the minimum height and the minimum necessary clearance, which allows you to move the station by dragging;
  
• The fuel tank capacity is 1500 liters.
  The tank of a special design was compactly placed on common skis, so that it represented a single unit together with the installation.
  The tank was equipped with modern fuel level sensors, indicators necessary for refueling, and breathing valves;
  
• The pumps are equipped with an automatic self-priming system with a capacity that allows filling huge pumps and suction mains in 1-2 minutes;
• Flow meters were also used in the installations, which on the one hand are tolerant to polluted fluid and accurately show the flow rate despite the inclusion, on the other hand, they can withstand the high pressure created by the station;
• Of course, we have provided a lighting system: outdoor (with powerful dust and moisture protection) and under the hood space;
• The stations were supplemented with unique suction mains: a diameter of 400 mm, minimal hydraulic losses, the length of the mains is 10 meters, special BRS, special filter with the ability to pass large inclusions up to 55 mm . 

Just a few stations of such scale are produced per year all over the world !!! Reliability, high level of quality and ergonomics of the installation were noted by all who saw it, starting from the suppliers of spare parts and components, to the customer respectively, who was very satisfied with the installation.
