DYNASET pumps can provide pumping power for seawater, drilling fluids, disinfectants, chemicals, and many other fluids in almost any environment. However, it is important to note that the pumped fluid and the usage environment can affect the requirements for the pump. DYNASET pumps are an excellent choice for subsea operations because their structure withstands ambient pressure at depth.
How Do Usage Environment and Pumped Fluids Affect Pump Material Choices?
The operating environment can determine the materials from which the pump should be made. For example, our subsea pumps’ center bodies and heads are made of stainless steel or aluminum bronze instead of aluminum, which is used in some of the basic models. This is because aluminum is not resistant to saltwater. In addition, the pumps’ internal components are engineered to resist saltwater.
Sealed or Non-Sealed Leakage Space?
All DYNASET pumps have a leakage space that is not sealed in the basic models. The pumps have small leakage-detection holes, which make potential leaks easier to identify. The leakage space can remain open if the pumped liquid allows it and the hydraulic oil used is not hazardous to the environment. In subsea conditions, the open leakage space allows ambient pressure to provide important support to the pump seals at depth.
In some cases, the leakage space must be sealed. This can easily be done, as the leakage-detection holes are equipped with threads. In subsea conditions, sealing can be achieved with a pressure-compensated bladder attached to the leakage-detection holes. The bladder prevents leaks from entering the environment and provides the necessary support for the seals when ambient pressure cannot reach them.
Correct Materials and Maintenance for Different Chemicals
DYNASET pumps can also be used for pumping various chemicals. DYNASET personnel and authorized dealers can provide accurate information about the chemical resistance of our pumps. The easiest way to find out whether your fluid can be pumped with a DYNASET pump is to contact us via the form below.
