General The DICKOW-pump, type SCM, is a one or multistage, self-priming 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 ...
(2) Field of application The side-channel pumps are self-priming 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 ...
(2) The DICKOW-pump, type WPM, is a single or multistage selfpriming side channel pump in horizontal construction.
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 self-priming 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).
The weakest link with regard to potential
environmental damage in the case of centrifugal pumps, is the
shaft sealing, because there is always some inherent emission
from mechanical seals.
