Application of a TOYO GR 15 H-3 on landfill site

Application of a TOYO GR 15 H-3 on landfill site

The waste management company Buhck GmbH & Co. KG operates sorting and recycling facilities, gravel pits, a composting plant, and Class 2 and 0 landfills on 70 hectares of land.

Before the first two Class 0 landfill sections could be built and operated, the naturally occurring soil had to be removed. During the soil removal and landfill construction phase, the challenge was to continuously pump out not only the accumulating strata water but also the precipitation water. The situation was further complicated by the fact that the water to be pumped out was highly contaminated with sediments. Since further soil removal work for new Class 0 landfill sections is being driven forward and it is desired to prevent accumulation of accumulated strata and precipitation water adjacent to already constructed landfill sections, a collection and settling basin was constructed outside the landfill at the low point.

Here, Buhck decided to use an extremely wear-resistant and powerful armored pump from TOYO. The TOYO GR 15 H-3 is ideally equipped for these challenges and can pump the medium with a grain size of up to 25 mm without any problems over a conveying distance of approx. 170 m into another settling basin located approx. 17 m higher.

The water settled there and now largely free of sediment is pumped by a Grindex Master H via an approx. 200 m long DN 110 HP-PE pressure pipeline into the adjacent sewer network. The water law permit required for the discharge was applied for and obtained in advance.

TOYO GR - the inexpensive entry into the world of TOYO submersible pumps!

The Toyo GR submersible pumps with agitator have been designed to pump solids and abrasive media in high concentrations. The GR pump is a centrifugal pump with a semi-open impeller and a special agitator. The rotary motion from the agitator provides homogenization of sedimented solids in the liquid to make them pumpable in high concentrations and continuously. A robust construction of wear-resistant material with a special design gives the pump unsurpassed durability and high operational reliability. The impeller, wear plates and agitator are made of high alloy chromium steel castings (24 to 28% chromium). A strong, short shaft supported by a series of specially designed, double mechanical seals running in an oil bath, guarantees sealing for the toughest requirements. The pump can be used for low water level applications (minimum immersion depth is above the impeller) due to its jacket cooled design. Maintenance and repair of the pump are easy to perform. The GR 15 to GR 30 models have an adjustable wear plate. Performance optimization by adjusting the gap dimension on the impeller is easy to realize. Furthermore, the TOYO GR series has an integrated thermal sensor. The solid concentration of the medium can be up to 30 percent by weight, the grain size can be realized up to 40mm and the temperature of the pumped medium can be up to 60°C. The pH value of the fluid can be between 4 and 9.5.
