HZM & - Multi Stage Centrifugal Magnetic Driven HZSM , Multi Stage Self-Priming Medium Flow with High Pressure
|
Multi Stage centrifugals are used to produce higher pressures than could be efficiently obtained from single stage centrifugal pumps. Multi impeller stages add pressure for each impeller. HZM and HZSM pumps are magnetic driven to eliminate the need for a mechanical seal or packing.
Applications
HZM/HZSM pumps offer exceptional benefits to the chemical, petrochemical and allied industries and fulfill all environment protection rules especially when handling toxic, explosive or other dangerous liquids that react on contact with the atmosphere. The containment shell replaces single or double acting mechanical seals with external fluid reservoirs and the necessary control equipment. Leaking shaft seals causes 90% of pump failures, the sealless design increases reliability and reduces maintenance costs. The pumpage is hermetically sealed to the atmosphere by the shroud - no shaft sealing is required.
Self Priming HZSM type is used in tank farms, for unloading rail cars and trucks, filling of storage tanks and other applications where priming of empty suction pipes is required. HZSM-type offers special benefits of low NPSH-values and gas-handling to liquefied gas applications. Typical application is filling of LPG-trucks and rail cars in refineries.
