Grundfos delivers more than an efficient solution

Overview

Grundfos has supplied SE and SL wastewater pumps for pumping stations owned by CUP Focsani, the Focsani Municipal Water Company, and in the following installation these have proven their high efficiency and non-clogging abilities. The pumping stations serve the wastewater pumping requirements in Vrancea County, Romania.

The situation
As many other water utilities in Romania, CUP Focsani is focused on improving and developing the water and wastewater facilities in its area. To that end, CUP Focsani received EU funds a few years ago in order to start investments in five cities and three villages in Vrancea County, which had been divided into different tenders, depending on the specifications for each project. For wastewater networks and wastewater pumping stations, the two tenders were won by two experienced construction companies. The main requirement for the customer was for a high efficiency and non-clogging solution. Grundfos was selected as a supplier.


The Grundfos solution
These projects gave Grundfos an opportunity to demonstrate that the SL/SE range of wastewater pumps has the best overall efficiency and non-clogging capabilities. All 38 pumps that have been supplied are from the SL/SE range using S-tube or SuperVortex impellers, installed 1+1 in wet pits on auto coupling, except for one pumping station which proved to be the most challenging in the project. At this site, there was a requirement for 15l/s flow with a very high head of 85WCm. The highest efficiency solution for this particular pumping station was offered by Grundfos with two SEV wastewater pumps with SuperVortex impellers installed in series; one on an auto coupling (wet) and one on a base stand (dry). The total P2 for these pumps in series connection is about 33.5kW for 15l/s at 85WCm and 49Hz compared with the best competitor offer, which had 34.3kW for 15l/s at 84WCm and 50Hz. This was below the duty point required.


The outcome
Except for a few minor adjustments with the control panel, the SE and SL wastewater pumps with S-tube impellers have operated without a single clogging incident since installation. The success and quality of the solutions can be demonstrated by the new contracts already signed with those customers for other important projects. In line with the approach generally taken by Grundfos, the goal with this project was not only to sell products. Grundfos demonstrated to the end user and direct customers (contracting companies) that Grundfos is more than a pumps supplier – Grundfos is ready and open for any demands and challenges presented by the installation.

I believe it is important to make
the customer understand that
the best technical solution is the
‘cheapest’ for the future – and not
the lowest investment value. This
is the reason that a salesperson
must discuss price only at the end
of negotiation, in order to be sure
that the customer understands
the benefits when compared with
his needs,
