Dosing pump technology from sera
May 2011
Valves, Actuators & Pump Control
Top operational safety with hazardous chemicals in the production of man-made fibres.
A large Austrian company, a world leader in the manufacturing and marketing of man-made cellulose and Viscose fibres, recently needed a dosing pump for 36% hydrochloric acid solutions suitable for large delivery volumes.
Operational safety even at high flow volumes
The customer requirements for this pump, designed for a delivery volume of 4800 litres per hour, included optical diaphragm monitoring, adjustment of the stroke length when the machine is stopped or running, an integrated compensation valve, overcoming high counter pressures, low residual pulsation and high dosing accuracy.
The experienced application engineers from sera were able to meet all customer demands with a multiheaded piston diaphragm pump from the 410.2KM model series. The sera solution was considered superior to others because of the outstanding economic and technical aspects.
Decades of experience in handling critical media
Dosing and delivery of aggressive chemicals such as hydrochloric acid presents special demands on the material and the operational safety of a diaphragm pump. The dual diaphragm technology, registered by sera for patent approval in the early 1950s, was, even at that time, able to offer safe and reliable pump technology for applications like this.
Over the decades, sera has expanded this expertise continuously and is today able to offer powerful, economic and durable product solutions for large delivery capacities.
