WHY CHOOSE US?
Industrial pumps operating in corrosive environments are subject to a number of issues due to the aggressive conditions under which they work. To address these problems, Darimpianti carefully selects the pumps and materials appropriate to the type of corrosive fluids existing in the working environment, including taking preventive measures such as corrosion protection, regular monitoring and routine maintenance.
Corrosion
Persistent exposure to corrosive chemicals can cause damage to the pump casing. Corrosion can erode the internal and external surfaces of pumps, thereby reducing their efficiency and life span.
Accellerated wear
The corrosive action of fluids can accelerate the wear of pump moving parts, such as shafts, bearings, and seals. This can lead to reduced performance and frequent maintenance or replacement of parts.
Leaks
Corrosion of seals and gaskets can cause leakage of fluids. Leaks not only result in lost material, but also result in contamination of the surrounding environment or cause damage to adjacent equipment.
Sealing
Corrosive substances can affect the tightness of pump connections and joints. This can lead to pressure loss or unwanted air ingress, thereby compromising the efficiency of the pumping system.
Clogging
Some corrosive substances can form solid deposits or precipitate that can clog the pipes and the internal components of pumps, which can reduce the flow of fluids and block or interrupt pump operation.
Material compatibility
Incorrect material selection or choosing materials that are not fully compatible with the fluids can still lead to corrosion problems or undesirable chemical reactions.
