BBA: Environmentally friendly high flow pump unit


BA-C500 Boskalis  (2)Boskalis Technical Service Nederland manages several mobile pump units with high and ultra high flows. Boskalis clearly prefers environmentally friendly equipment and has very specific requirements from their pumps which include;

  • The pump must have a minimum capacity of 5000 m³/hr and a pressure in excess of 3 bar;
  • Excellent suction capabilities (NPSHr curve) and suitable for use as a dewatering pump;
  • High fuel efficiency combined with the lowest exhaust emissions;
  • The pump unit should fit into a 20 ft. container for easy transport;
  • The maximum weight should be no more than 12,000 kilograms.

Boskalis has a number of widely divergent projects around the globe. This makes multi-functionality and ease of logistic handling important factors in the purchase of new equipment. In addition, durability and corporate social responsibility are central to the company’s values. As an example Bas van den Brand, a technical superintendent with Boskalis Nederland, mentions the topic of weight. “For a pumpset of this size, 11 to 12 tons is usually the maximum permissible due to limitations in handling on site. Also, the soil layers can be substantially compacted and cannot always carry the weight”.

The Solution
Early in October 2014, Boskalis Nederland officially commissioned the delivery of a BBA high flow pump unit of the type BA-C500S11 D711 with a very attractive efficiency of 86%. The auto prime pump provides a capacity of 5500 m³/hour (24000 US GPM) and a maximum head of 37mwk (120 ft). The pump is driven by a modern Stage IV Volvo Penta diesel engine; the TAD1374VE. This provides a power of 375kW and delivers the lowest specific fuel consumption in its class (207 g/kWh). Exhaust gas is treated using AdBlue®. It is fully equipped with the newly developed, extremely silent and light weight canopy and its dimensions ensure that it fits into a 20 ft. container without any problems. The total weight of the pump unit is just 10.800kg!

The Result
The new BA-C500S11 has now been deployed in a first project in Muiden. The A1 highway is being widened and partially rerouted. The Boskalis Nederland employees on-site are very impressed with the pumping performance, especially with regards to the low noise emissions.

BBA Pumps has decided to include this pump unit in its standard product range.
