Magnetic Coupled Sealless Process Pumps & API-685

Multistage Centrifugal Pumps Type HZSM/HZSMA

Dickow Pumps Product PageGeneral
Magnetic coupled DICKOW-Pumps of series HZSM / HZSMA are of sealless design. The containment shell forms a closed system with hermetically sealed liquid end. The properties of the inte grated side channel stage allows the handling of entrained gas and operation under suction lift conditions.

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.


Process Pump ace. to API 685 series PRM

Dickow Pumps Product PageGeneral
Magnetic coupled DICKOW-pumps of the series PRM according to API 685 are heavy duty sealless pumps. The containment shell forms a closed system to separate the pumped liquid from the atmosphere by confined gaskets. The equipment (including auxiliaries) is designed and constructed for a minimum service life of 20 years (excluding normal wear parts) and an uninterrupted operation of at least 3 years.

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).

Side Channel Pumps with Magnetic Coupling (Sealless)

Item # SCM, Side-channel Pumps Type SCM

Dickow Pumps Product PageGeneral
The DICKOW-pump, type SCM, is a one or multistage, selfpriming horizontal side-channel pump with magnet coupling. The side-channel pump with its high differential head has the advantage of operating more economically than normal centrifugal pumps applied for low capacity and high heads. Due to these facts, the side-channel pumps are appropriate to solve many pumping problems in the chemical and petrochemical process. The SCM-pump is a heavy duty unit for handling clean pumpage without solids. Sealless magnetic driven pumps are designed to improve plant's and personnel safety, especially when handling toxic, explosive or other dangerous liquids which react on contact with the atmosphere. For all such services, the static shroud replaces double acting mechanical seals with external fluid reservoires or barrier fluid circulating systems. Due to the fact that 90% of pump failures and required service base on leaking mechanical seals, the sealless design will save maintenance and spare parts costs remarkably. Considerable are the total cost savings of ownership.


Vertical Selfpriming Side Channel Pumps Type WPV/SMV

Dickow Pumps Product PageField of application
The side-channel pumps are selfpriming and operate more economically (better efficiency) than normal centrifugal pumps, when handling low flows and high heads. Due to these facts, the side-channel pumps are appropriate to solve many pumping problems in industrial processes. They can be used for almost all liquids which are free of any abrasive solids and of suitable viscosity. The vertical side-channel pumps are suitable especially for tank farms with underground storage tanks with a diameter of max. 2,5 m (8.2 ft). The construction of the pumps enables an installation directly on the dome cover. That means, suction lift is only slightly above the tank diameter and the priming pipe can be kept short. For handling toxic, explosive and other dan gerous liquids in chemical and petrochemical industries, a sealless pump design with perma nent magnetic coupling - without shaft duct to the atmosphere - is also available. Since the static containment shell forms a closed system with hermetically sealed liquid end, an operation with zero leakage is granted. These pumps are maintenance free because no shaft sealing is provided.


Side-channel Pumps with Magnetic Drive Type WPM

The DICKOW-pump, type WPM, is a single or multistage selfpriming side channel pump in horizontal construction.

Dickow Pumps Product PageField 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).

Side Channel Pumps with Shaft Sealing

Selfpriming Side-Channel Pumps Type SC-PN40

Dickow Pumps Product PageThe DICKOW-pump, type SC, is a one or multi-stage, selfpriming horizontal side-channel pump. The side-channel pump with its high differential head - also at low speed - has the advantage of operating more economically than normal centrifugal pumps applied for low capacity and high heads. Due to these facts, the side-channel pumps are appropriate to solve many pumping problems in the chemical and petrochemical process. The SC-pumps are also able to prime empty suction lines after initially filling with liquid before start-up. The maximum allowable operating temperature is 240 C (465 F).


Multistage Centrifugal Pumps with Shaft Sealing

Centrifugal Pumps Type HZ/HZA

Dickow Pumps Product PageGeneral
HZ / HZA-Pumps are applicated in the industrial and municipal water supply, in pressure increas ing plants, for handling condensates, for boiler feeding, as firefighting pumps and for various other applications.

The type HZA of end suction design has been developed for operating conditions with low NPSHA-values. The wear resistant SiC-sleeve bearing on the suction side reduces the maintenance costs because there is no second mechanical seal required.

The performance range is subdivided to achieve best efficiencies for all service conditions.

With a wide selection of materials and the possibility of applying several shaft sealing systems as well as a hermetically sealed permanent magnetic coupling, the HZ / HZA- pumps are suitable for handling almost all kinds of liquids which are free of abrasive solids and of suitable viscosity.
