Designed for mounting on non-selfpriming centrifugal pumps
The DESMI priming ejector is designed for mounting on non-selfpriming centrifugal pumps thus making the pump unit self-priming. In order to make the unit work, the delivery pipe has to be shut off, e.g. by means of a non-return valve
Compressed air will flow through the ejector and create a vacuum in the pump casing and suction line. After priming, the pumps will build up pressure in the discharge line which will activate the presure switch. The presssure switch then disconnect the power to the solenoid valves and the priming stops automatically.
At a fluid pressure of e.g. 10 m / 33 ft total head the unit will disconnect automatically (adjustable from 3 - 100 m / 10 ft - 328 ft total head). If the pressure drops to less than 10 m / 33 ft total head, the unit will automatically start functioning until a counter pressure has been reestablished.
The DESMI B114 priming pump is driven by its own electric motor
The DESMI priming pump is designed for mounting on non-selfpriming centrifugal pumps thus making the pump unit self-priming. In order to make the unit work, the delivery pipe has to be shut off, e.g. by means of a non-return valve.
The filter prevents solids from penetrating the priming pump, and the non-return valve (H) secures that back flow is avoided when the priming pump is stopped.
If the main pump has positive suction head the solenoid valve stops water from running through the priming pump unexpected when the pump and priming pump are stopped.
The priming pump is provided with a supplementary tank at the discharge side of the priming pump which has to be filled with water prior to starting the system. During priming, the air escapes while the water circulates in the pump procuring sealing and cooling.

Transport and treatment of waste water are important tasks in a modern society
The waste water must be transported from residential areas and industrial companies to the waste water treatment plant, that need to optimise the way it treats wastewater with the least possible impact on people and nature.
Transportation of waste water is full of challenges. Energy optimisation, design, installation and maintenance are just some of the issues that must be addressed when establishing such systems. The waste water must be transported from residential areas and industrial companies to the waste water treatment plant, that need to optimise the way it treats wastewater with the least possible impact on people and nature.
DESMI has many years of experience in the swimming pool/public baths (aqua parks) industry.
To ensure low energy consumption and pumps with high efficiency levels, we have developed new, highly effective, all bronze swimming pool pumps at reasonable prices.
Bronze is the best material
The choice of all bronze is very deliberate. Bronze is definitely the best material when it comes to pumping chlorinated water. The efficiency remains virtually unchanged throughout the pump's lifetime, and since it is substantially higher for the new pumps, in many cases, a smaller pump can be utilised, which gives additional savings.
DESMI's experience with power plants is partly connected to Denmark's leading position with Combined Heat & Power Plants (Co-generation) as well as Waste-to-Energy Plants, Biomass Plants etc.
