Flow measurement and control instrumentation are all the “clean side” of the system measuring pure hydraulic oil that doesn’t wear out the instrumentation. Lifetime of the instrumentation normally over 100 000 hours.

Extremely accurate and fast flow and mix ratio control

System is hermetically closed and does not have any wearing seals.

Only system available wit pre-pressuring function. The pump system pre-pressurizes the supply lines to the working pressure before opening the spray valves. This enables that the flow of both materials are constant from the beginning of the cycle and indicates that if there is any leaks in the system.

When comparing the down time, maintenance cost and operating efficiency during the first 18-24 months of production, the system running costs including the capital investment is the lowest in the markets.

Moderate purchase cost

Air-motor actuators are reliable when the supplied air is clean.

Inaccurate output flow. When the piston changes the moving direction, the output will momentarily go to zero causing pulsation. Therefore in each pump cycle for a while the mixing ratio between the base material and hardener is incorrect.

Due to the pulsation, the flow control accuracy must be kept inaccurate to prevent the alarms in normal operation.

Due to the wearing of the seals, the output of the pump will change in long term.

Flow meters became inaccurate due the wearing and crystallization of the hardener. Actual flow rate and mixing ratio with worn equipment is +/- 10%.

Stabilisers increase the pulsation and the control limits for the flow controls must be kept wide.

High need for maintenance because the materials contain a lot of abrasive particles that will wear the seals, cylinders, check valves and piston shafts.
