BBA Pumps On A1 Road Widening

In October 2014, Boskalis Nederland commissioned the

delivery of a BBA BA-C500S11 D711 high flow pump unit

with an operating efficiency of 86%.

The auto prime pump provides a capacity of 5500 m³/

hour (24000 US GPM) and a maximum head of 37 mwk

(120 ft).

The pump is driven by a Stage IVVolvo Penta TAD1374VE

diesel engine. This provides a power of 375 kW and is said

to deliver the lowest specific fuel consumption in its class

(207 g/kWh). (Exhaust gas is treated using AdBlue).

It package is extremely quiet, lightweight and sized to

fit into a 20 ft container. The total weight of the pump unit

is just 10.800 kg.

This met Boskalis Technical Services requirements for

high capacity, high efficiency, able to fit in a 20 ft container

and weighing less than 12,000 kg.

The set was quickly deployed in a first project inMuiden

where the A1 highway is being widened and partially
