The HÜDIG customer Mr. Korupp of Ernst Lütjens Kieswerk (gravel quarry) in Sankt Peter Ording/Germany had requested the technical support of HÜDIG after several technical disappointments in the operation of pumps of other suppliers. He decided in 2008 using a TOYO Heavy-Duty pump Type DP 15 according to dimensioning of HÜDIG. Mr. Korupp does surely not operate a huge gravel quarry, but he could raise his annual capacity to an average of approx. 15.000 m³/h.

From 2008 until today this gravel quarry can proof a total capacity of 90.000 m³. The most interesting point is that the investment of the TOYO DP 15 has paid off in the meantime – in regard of the low cost for maintenance and service. Based on the calculation of the conveying capacity the detailed costs for maintenance and installation were easy to indentify and they were 0.09 €/m³ only.

Consequently it is rightly so to claim – TOYO pays off!
