pumped and the specific chemicals and materials in the water should be taken into consideration when selecting a pump A thorough review of the construction materials of the exposed pump components should be performed to ensure compatibility with those chemicals This includes the impeller pump casing O rings gaskets cable sheathing motor housing fasteners and mechanical seal Cast iron or aluminum components can quickly deteriorate and cause catastrophic pump failures in very low or high pH levels whereas a stainless steel or titanium pump may last for years in the same environment Industrial processes such as paper pulping produce wastewater containing many different chemicals including solvents and acids The chemical compatibilities with all the exposed pump components should be considered through available chemical compatibility charts to prevent corrosion Pump companies typically do not warrant against corrosion erosion or chemical incompatibility so choosing a pump with improper materials of construction for the application can be costly Pump motor protection devices A submersible pump of high quality will have protection designed into the pump to prevent failures from occurring Electrical failures and water incursion are the two most common failures of a submersible pump Running a submersible pump dry having improper source voltage and other electrical and mechanical failures can cause permanent damage to a submersible pump motor These failures can be eliminated if the pump is designed with a thermal motor protector This protects the pump motor by monitoring the internal motor temperature and current then shutting down supply voltage to the pump using a bimetallic switching device Once the temperature goes back to normal operating conditions the pump will run once again Protection from water incursion is also very important Choosing a pump with a high quality mechanical seal will keep water from getting in the motor through the wet end where an anti wicking cable entry will keep water from wicking into the motor through a nicked or cut power cable Notice of sale and auction by secured creditor of Cloudburst Solutions LLC a Delaware

technical drawings and other due diligence materials will be provided upon the interested parties providing an executed non disclosure agreement and proof of ability to perform thereunder and at the scheduled auction At the sale only cash or cashiers check will be accepted save and except the credit bid of the foreclosing secured creditor WCG Holdings S A and must be paid within one hour of the time of bid acceptance at the sale Duty point and efficiency The duty point is the flowrate and total dynamic head TDH at which the pump will operate in a particular application The TDH for a submersible pump is comprised of the static head or vertical lift in feet that will be pumped up as well as the friction loss head due to the flow of water going through the piping fittings valves etc expressed in an equivalent measure of feet of head A pump distributor can help determine the TDH of your application The best efficiency point BEP is the point at which the pump is operating at maximum efficiency When selecting a pump for continuous duty dewatering and permanent sewage and wastewater applications the duty point should be within 30 of the BEP of the pump Running pumps outside this range can lead to higher running costs cavitation damage excessive vibration and reduced mechanical seal life For intermittent duty temporary dewatering applications this range can be widened but it is recommended to stay on the performance curve and it is good practice to avoid running the pump within the first or last 10 of the curve Mike Klimes is an application engineer for Tsurumi America
