NIKKISO ® Non-Seal Pump Centrifugal canned motor pumps.

NIKKISO Non-Seal Pump – Introduction NIKKISO Non-Seal® Pumps. NIKKISO began with the production of centrifugal canned motor pumps in 1956, making it one of the first companies in the world to produce these pumps commercially, and it continues to do so today. Originally developed for the nuclear industry, the centrifugal canned motor pump has been developed further over the years and adapted to a wide range of industrial applications. NIKKISO has taken a pioneering role in these developments since its founding. For example, the E-Monitor is the most advanced system of its kind for the...

NIKKISO Non-Seal Pump – Advantages NIKKISO Non-Seal Pumps. The advantages at a glance. Safe No gaskets – no leakages. Through a double safety enclosure, consisting of an internal stator lining and an external pressure-resistant stator housing, leakages and thus harmful impacts to the environment are avoided. This minimizes both immediate and long-term risks for personnel. Quiet and low-vibration A fully encapsulated system without motor fan or exposed bearings enables low-noise and low-vibration operation. E-Monitor Monitoring of bearing condition during pump operation for the highest...

NIKKISO Non-Seal Pump – Markets Chemical industry NIKKISO is one of the leading manufacturers in the sealless pump industry for conveying hot oil. Non-Seal pumps are often used as transfer pumps for chemical fluids or for unloading rail vehicles. Refineries The applications for refineries include the conveying of catalysts for alkylation (sulfuric or hydrofluoric acid), natural gas condensates, benzene, acidic water, volatile hydrocarbons or Liquefied Natural Gas (LNG). Energy utilities In the energy sector, NIKKISO centrifugal canned motor pumps are used as seal water pumps, in...

NIKKISO Non-Seal Pump – Components The most important components for reliability and safety. E-Monitor The NIKKISO E-Monitor has been developed to determine the condition of the hermetically sealed pump bearings during pump operation. The position of the rotor is monitored while the pump is operating. Furthermore, the technically state-of-the-art monitor can be used for preventive maintenance relating to bearing wear. Display: – eparate wear display for axial and radial bearings S – neven wear of the front or rear bearings U – ump “ON” P – irectional monitoring D Advantages: – he...

NIKKISO Non-Seal Pump – Components Bearings-modular system NIKKISO bearings are slide bearings. The materials used range from various carbon graphites through polytetrafluorethylene (PTFE) to silicon carbide. The use of CG93, a mixture of carbon and silicon carbide, enables increased protection against wear without any brittleness. Shaft protection sleeves (hard-coated) The bearings are liquid-lubricated and designed with a groove for an improved supply of lubricant. Depending on application, the shaft protection sleeves are either plated with chromium or finished with a hardened material....

NIKKISO Non-Seal Pump – Components Motors. Reliable motors – Protection against leakages through seal-welded and 100% leakage-proof corrosion-resistant linings. They ensure that the supplied medium does not come into contact with the stator windings or the core of the rotor. – The complete outer side of the motor is encapsulated in a second leak-proof protective shell. – Increased operating reliability through the absence of dynamic seals. – Motor cooling and bearing lubrication through the supplied medium that is circulated in the area between the rotor and stator lining. – Motor windings...
