Overview of material selection based on pH scale (Image source: BBA Pumps BV)

Other factors which also need to be considered are temperature, oxygen and the chloride content.

Generally speaking; when the pH value decreases, the acidity increases and with it the corrosion reaction. Further, the higher the temperature or chloride content of the liquid, the higher the rate of corrosion.

The most common pump materials:

Customized advice and safety first Selecting the material for a pump based on the pH scale does not guarantee a corrosion-free solution. BBA Pumps has a materials compatibility guide available for pumping a range of different chemicals. This allows them to accurately determine the most suitable material for a pump.

There are other additional options for extending the life of a pump. For liquids with a high chloride content, they recommend providing the wet parts of the pump with an epoxy coating. This layer of coating protects the pump for a long time and in many cases also increases the pump efficiency by a few percent.

Safety first. During pump maintenance or a pump overhaul, it is important that the technician knows the pH value of the liquid that has been pumped. Strong acids and alkaline substances can cause burns and inhalation of chemicals can cause irritation to the respiratory tract. Care must be taken to ensure that the pump is always repaired by an authorized service company and that the technician is informed about the liquid that has been pumped before starting the repair work.

Hamworthy Pumps has been a supplier of large capacity pumps to the offshore industry for a long time. The C42B pumps for SBM operate as Sea Water Lift Pumps on the FPSO Cidade de Paraty and play a critical role in their operations.

BBA Pumps introduces a new settlement tank for mobile pumping systems and wellpoint dewatering. The settlement tank is now prepared for the installation of a Handy water meter and is equipped as standard with a composite grating cover and logo panels for own branding.

BBA Pumps is proud to introduce the first plug-in hybrid pump for well dewatering. It is often the case that power is not available at the job site when a new dewatering project is started. With the new plug-in hybrid PT pump, it is possible to start lowering the water table using the diesel engine, and once the power supply is available, it is easy to switch to the electric motor.

Tjaden, a dewatering company with more than 126 years of experience in groundwater management, has made a major investment in new pumps. The result is a great order for the delivery of twenty-five PT150 electric ​​wellpoint pumps.

BBA Pumps proudly introduces three new mobile pump sets. A new model canopy containing a clean and fuel-efficient 3.6 liter engine forms the foundation. The three different centrifugal pumps are familiar models from the BA series with improved performance.

Pump service must be fast and painless. Therefore, the benefits of buying service kits are obvious and Hamworthy Pumps is experiencing an increasing demand for its various overhaul- and seal kits.
