High Capacity Flood Control Pumps

 In cases of heavy rainfall that cause large volumes of stormwater and possible flooding, it is important to respond quickly. Diesel powered, high capacity flood control pumps from our BA series are designed for these challenging circumstances. BBA Pumps offers a wide range of mobile high capacity pumps which can be mounted on a trailer for an even faster solution.

Benefits for you

• Easy handling thanks to the compact design and lightweight mobile units
• High volume pumping with maximum flows to 34,000 US GPM
• Fast priming and re-priming due to the inbuilt vacuum assisted system
• No noise due to the BBA Pumps sound attenuated canopy

High flow pumps at work

Large mobile water pumps can be used in a wide range of applications. From being used in flood control to a set up for dredging projects, the BA series high flow mobile pumps are just incredibly versatile. To give more insight and to see the pumps at work, watch these video’s below!

High flow pumps 16" to 28"    

When you need to respond to a major flooding, high flow pumps are the best solution. Tackling floods often requires the use of 16-inch and larger diesel driven pumps. BBA Pumps is a specialist in large mobile pumps for tackling floods. The technical information below applies to the four models of high flow pumps: BA400G, BA500G, BA600G and the BA700G.
 

Standardized high flow pumps

The standardized mobile pumpsets from BBA Pumps are specified in detail. Quality control takes place throughout the entire production process, from the initial drawings to the FAT protocol. Unlike customer specified products, standardized pumps are manufactured based on a forecast of the market demand. Diesel driven high volume pumps are supplied to comply with the current worldwide legislation that governs emissions. All production drawings are available for review by the client upon request. The manufacture process runs according to a fixed production schedule and quality plan. Parts drawings are available for the centrifugal pump, the vacuum system and the canopy. An extensive user manual (with a choice of seven languages) and a 16-language warranty booklet are included. Standardized BA pumps are covered by the internationally applicable 4-year manufacturer's warranty.
 

The high flow centrifugal pump

The dry prime centrifugal pump is equipped with a mixed flow pump impeller with a large free passage. The pump curve is based on continuous use and follows the international standard ISO 9906. The pump efficiency at the Best Efficiency Point is 85% or higher. The high volume pumps are designed to deliver an excellent NPSHr curve so that the pump can run cavitation-free even at a high suction head.
The centrifugal pump has a number of innovations to enable it to operate as a dry self-priming pump without the risk of damage or compromising its working lifespan:

• The mechanical shaft seal has been specially developed by and for BBA Pumps. Dry self-priming pumps have to cope with alternating pressure and vacuum differences in the seal chamber.
• The bearing frame is equipped with two separate oil chambers, one for bearing lubrication and the other for cooling the mechanical seal during dry running. Both oil chambers are equipped with sight inspection glasses and drainage and filling points on one and the same side.
• Other innovations include a drainage channel and oil splash plate. Special features help prevent environmental pollution and ensure that the pump can still continue to run should the mechanical seal become damaged.

For the optimal inflow of the liquid to be pumped, the suction connection of the pump has a larger diameter than the pressure connection. The suction connection is equipped with a heavy mounting bracket, a vacuum gauge and a large inspection hatch that provides easy access to the pump impeller. There is also a large inspection cover on the pump housing. The pressure side of the centrifugal pump is equipped with a manometer.

High volume pumps vacuum system

The BBA Pumps vacuum system consists of three components:

• A mechanical float box on the suction side of the centrifugal pump.
• A non-return valve on the discharge side to ensure that no air is sucked in via the pressure line during suction.
• MP100 vacuum diaphragm pump with an air capacity of 59 CFM.

The MP100 is a double diaphragm pump with a V-shape (2 x 29 CFM) so that in the event of an emergency or during a technical failure, one diaphragm pump can always be drawing water in. A diaphragm pump can pump condensation and a limited amount of water. The maximum vacuum range of the vacuum system is 8,5 meters.

Operation: When the diesel engine is started, the reduction gearbox is in a free-running position, so that the main pump does not rotate while the vacuum pump sucks in the liquid until the pump housing is filled. The main pump then switches on automatically and the vacuum pump stops priming. Switching off is done vice versa so that the unit comes to a smooth stop and the risk of water hammer is minimal.

Sound attenuated canopy for high volume pumps

The diesel engine is supplied as standard in a sound attenuated canopy and the pump is placed outside on the frame (the BA400G is completely enclosed). The canopy frame is completely hot dip galvanized, guaranteeing a highly durable end product. Noise emissions are significantly reduced, with the noise level dependent on the engine power which is shown on the datasheet. Other features of BBA Pumps enclosures for high volume pumps;

• The doors are made of composite and can be locked with identical door locks
• The composite fuel tank reduces the risk of bacteria formation in the diesel
• The bottom tray is leak-proof to prevent oil or fuel from leaking into the environment
• Forklift pockets and lifting eyes ensure optimal material handling
• The casing is fitted with work lights on the outside and inside the canopy

The canopy can easily be fitted with a pull-up frame for transport on a truck with a hook arm. Other options such as an external fuel tank, doors in your own company colour or telemetry are always possible.

FAT and SAT for high volume pumps

BBA Pumps is fully equipped to carry out Factory Acceptance Tests. We can test the largest mobile high volume pumps at our test facilities. We also have significant experience with Site Acceptance Tests. We have completed major flood control projects worldwide. Our pump specialists are ready to provide training at our training centre in the Netherlands or on location.
