Applications
Magnetic driven HZSM / HZSMA-pumps are designed to improve plant and personnel safety, especially when handling toxic, explosive or other dangerous liquids which react on contact with the atmosphere. For all these services the contain ment shell replaces double acting mechanical seals with external fluid reservoirs and the neces sary control equipment. HZSM / HZSMA-pumps therefore offer exceptional benefits to the chemi cal, petrochemical and allied industries and fulfill all environment protection rules. Due to the fact that 90% of pump failures are caused by leaking shaft seals, the sealless design increases the availability and reduces maintenance costs. The HZSM-type is used in tank farms, for offload ing rail cars and trucks, filling of storage tanks and other applications where priming of empty suction pipes is required. Considering low NPSH-values, gas handling capability and sealless design, the HZSMA-type offers special benefits to liquified gas applica tions. Typical application is filling of LPG-trucks and rail cars in refineries.

Applications
Magnetic coupled PRM-pumps improve plant and personnel safety and reduce maintenance costs, because 90% of these costs are caused by lea king seals. The PRM-pumps will handle nearly all kinds of liquids in the chemical and petrochemical industry, in refineries and industrial heating plants. Especially liquids which are toxic, flammable, bad smelling or which react on contact with the atmosphere, that means if no leakage is acceptable. For all these services the containment shell replaces the double acting mechanical seal with its external flushing system and the related control equipment. The performance range of the PRM-pumps is subdivided such that the best efficiency is guaranteed for all service conditions. The capacity goes up to 900 m3/h (4000 USgpm), the differential head up to 150 mLC (500 ft).

Applications
Magnetic driven KM-pumps are designed to improve plant and personnel safety. Especially when handling toxic, explosive or other dangerous liquids which react on contact with the atmosphere. The KM-pumps operate maintenance-free and their containment shells replace double acting mechanical seals with external fluid reservoirs and the necessary control equipment.
Maximum capacity appr. 70 mVh (300 US-gpm), differential head 65 mLC (213 ft). Temperature range - 30°C to 200°C (390°F), working pressure 16 bar (232 psi).

Applications
Magnetic driven NM-pumps are designed to improve plant and personnel safety, especially when handling toxic, explosive or other danger ous liquids which react on contact with the atmos phere. For all these services the containment shell replaces double acting mechanical seals with external fluid reservoirs and the necessary control equipment. NM-pumps therefore offer ex ceptional benefits to the chemical, petrochemical and allied industries and fulfill all environment protection regulations.
Maximum operating temperature 240°C (465°F) for the standard NMB/NML-type. The NMW-de- sign with no internal circulation and dead-ended magnet end allows temperatures up to 350°C (660°F). The maximum allowable working pressure is 25 bar (364 psi).

Field of application, general
Circulation of solvents in the chemistry and photo industry, pumping of toxic liquids in chemical industries, circulation in loop circuits. The static shroud forms a closed system with hermetically sealed liquid end and ensures a service with zero leakage. As shaft sealing is eliminated no maintenance is required. Owing to its selfpriming construction, the pump can be mounted on top of vessels. Risk of leakage at connections below the liquid level and necessity of expensive vertical submersible pumps is therefore out of question.
Maximum allowable temperature 200°C (390F).

Application
The NKLs-HTM pumps will be applied as circula ting pumps in industrial heating plants. The performance range covers capacities up to 400 nf/h and differential heads up to 90 mLC in 50 cycles service.
The maximum allowable operating temperature PT is 340°C without additional cooling. The NKLs-pumps with the single acting N10q- seals can be applied when handling HTM with boiling pressure at operating temperature below the atmospheric pressure (<1 bar abs).

APPLICATIONS
The performance range of the NCR-pumps is subdivided such that acceptable efficiencies can be achieved for all service conditions. The maximum capacity goes up to 700 m3/h (3100 USgpm). Differential head up to 145 mLC (480 ft) at 2900 rpm and 220 mLC (660 ft) at 3500 rpm.
With a wide selection of materials and the possibility to install all shaft sealing systems according to API 682, DICKOW-NCR-pumps are suitable to convey nearly all kinds of liquids which are usual in the above mentioned industries. E.g. acids, lyes, chlorinated hydrocarbons, heat transfer media (HTM), all kinds of hydrocarbon fuels, liquid sulphur, melted plastics, bitumen etc.
If the application requires sealless pumps, consider also our magnetic coupled PRM-pumps according to API 685.
