MATERIALS HANDLING
KEEP ON MOVING Turning a batch process into a continuous one: why stop if you don’t have to?
Te end result is a complete system that provided an ideal solution to a customer from the chemical industry to counter any leaks that occurred and also the disadvantages of the batch dosing process. Combining and mixing different substances together is a common thing in the chemical industry. To make sure that the processes involved take place safely and efficiently, the correct dosing of the substances, at the right moment and in the right quantity, is very important.
A
BATCH PROCESS AND LEAKS One of Suurmond’s customers that is active in the chemical sector was faced with several problems concerning its dosing processes. To dose additives into a production process, the company employed a piston pump with a reservoir; a system that can be compared to a large syringe that is slowly emptied, i.e. batch dosing. Although this system was perfectly accurate, the piston seal was often found to be leaking. And dosing by means of a batch process also required the production process to be stopped frequently to refill the reservoir. Tis was simply an impractical situation.
A COMPLETE SOLUTION To resolve these problems, Suurmond supplied two suurDOS systems. Tis solution is a complete dosing system consisting of a suction connection, a duplex filter system (one filter working and one stand-by), a chemically
inert rotary positive displacement pump (a type mzr-6355 HNPM micro gear pump), and a mass flowmeter. All the components are integrated into a complete unit that is quick and efficient to install. To ensure optimum process reliability, this customer’s systems have full redundancy built in.

dding special additives to a chemical production process requires an accurate and reliable dosing installation. Terefore an expert in dosing technology decided to create a suitable solution for this task.
Te magnetic coupling of the micro gear pumps (hermetically sealed; free from leaks) rules out the possibility of leaks at the seal. Te use of a positive displacement pump has enabled additives to be added as part of a continuous process. n
