tolerance of tanks. Hired pump specialistsare commonly hired to carry out the following applications; ground de-watering, fluid movement, and unwanted water removal. Over-pumping chambers during pump station maintenance. Clean water, sludge and slurry pumping. Draining reservoirs (for example when it is being excavated or requires rebuilds.) Emergency backup in case a pumping station fails. At docks, ports, harbours and marinas (during cleaning, removal of unwanted substances and deposits, and dredging.) The pumping out of huge digester tanks during sewage works redevelopment Pumping during repairs and upgrades to treatment works.
Varieties of pumps that are used vary greatly depending on the required application, with rental companies of pumps which provide services for things such as one-off pump hire, to the design along with installation and management onsite for intricate plans and designs. Some also lease pumps for hydrostatic testing.
Hydrostatic testing involves water or another kind of liquid being pumped into a tank (or another kind of vessel or liquid holding unit/system) to check its tolerance of pressure. This liquid is often coloured with dye so it is more clearly visible
Pumps are used to fill the tank up until it reaches the ’test pressure level’. This is the point where the handling experts of the tank has any leaks or if the internal structure of the tank is flawed, corroded or worn, this is referred to as checking a tank’s ‘integrity’. The hydrostatic test will also serve to check if the tank will burst under pressure.
Hydrostatic testing is important because it would be a lot worse for everyone if the tank wasn’t fit for use and was used anyway, resulting in severe damages. After hydrostatic testing users and owners can have confidence when it comes to the durability of the tank.
Savings are made when repairs don’t have to be made later because of faulty tanks, or even replacing the entire tank (and potentially the contents too!)
Hydrostatic testing is also useful for testing things such as sewage treatment work’s tanks, water storage tanks, cooling water systems, boilers at power stations, and much more! Hydrostatic testing is frequently requested for checking that old and new systems and storage components are in working order.
