FLUX Pumps for Paints and Lacquers

Paints and Lacquers

The production of paints and lacquers follow a clear structure: each production step influences the next and determines the quality of the final product. Gloss, adhesion, viscosity – every parameter counts. However, the most important part is the filling or decanting process at the end of the process. That's where FLUX comes in.

When the wrong equipment is used, it can lead to poor filling or decanting, which in turn will quickly undo all the quality work that has already been done. Rely on the knowledge of professionals – FLUX is well-aware of the challenges of your industry and has the optimum solution for your individual requirements.

Application examples

Filling of viscous dispersion plaster

Viscous dispersion plaster requires filling with a pump from a production vessel into 2 gallon buckets. Measurement is done by a floor scale.

Application description:
The F550 S eccentric worm-drive pump with bearing flange is the perfect solution for high viscosity liquids. The pump is positioned into the production tank using a hoist. A mounting bracket is affixed to the motor to make lifting safe.

The operator turns on the F550S pump transfers the liquid with ease into a bucket placed on floor scale via a PVC hose. When the scale reaches the desired value, the F550S is switched off manually by the operator. This can also be done automatically with a relay and scale capable of outputting a signal.

The eccentric worm-drive pump is tried and tested, proving that even with abrasive media, the F550 is capable of handling thick liquids while delivering a smooth, pulsation free flow. A heat-hardened or hard chrome-plated rotor should be utilized in these applications to ensure a long service life.

Pumping of finger paint

Finger paint needs to be pumped from various containers, e.g. buckets, lidded pails, drums or IBCs, via an existing piping system, as well as through hoses throughout the processing facility.

Application description:
Finger paints are fairly thick to paste-like and sometimes thixotropic. These kinds of liquids typically do not flow into a pump inlet freely.

Since a self-priming, air-operated diaphragm pump with compressed air motor can also draw in and pump viscous media, these are ideal for use in this scenario. It makes no difference what type of container the medium is being drawn in from. The medium is pumped into the intended container or system via a pipe and/or hose system.

Since the viscosity of the finger paint increases the backpressure in small diameter piping, a 4 series FLUX drum pump cannot be used. In order to supply a cost-effective solution, an air-operated diaphragm pump was selected.

The 1:1 ratio allows the pump discharge pressure to match that of the delivered air pressure. Up to 125 psig is possible. The paints are subjected to minimal shear forces due to very gentle pumping.

Pulsations can be minimized with the use of a pulsation damper.

Our air-operated diaphragm pump can be switched on and off by opening and closing the compressed air supply. Alternatively, it can also be shut off with a valve that simply closes the pipe/hose system at the pump end. In this scenario the air-operated diaphragm pump is dead-headed and simply stops. This capability allows the operator to work the equipment at a safe distance.

Solvent Transfer

A variety of solvents require filling into canisters from IBCs with predefined fill quantities.

FSV121-1 Ex switching amplifier
7/8" Universal, groundable chemical hose
Compression gland

Application description:
Before switching over to FLUX drum pumps, the customers process for emptying totes was to place a canister underneath the bottom outlet and open the valve. This frequently led to the canisters being over or under filled which was resulting in wasted profits and/or a mad customer. With FLUX, this issues are now a thing of the past!

The FLUX F430Ex S drum pumps with mechanical seal and appropriate Ex certification are perfect for low-viscosity, particularly aggressive and highly flammable media. A single point grounding lug allows for the equipment to be operated safely in hazardous areas.

The filling process is controlled by a semi-automatic filling system that FLUX has designed specifically for these application. It consists of a drum pump, motor, flow meter, FLUXTRONIC® evaluation electronics, and switching amplifier.

With the external FLUXTRONIC® evaluation unit, an operator can automatically fill the predefined quantity selected at the push of a button. After the filling process, the drum pump switches itself off and the process can be repeated. What you get is the proper amount of liquid needed each and every time the pump is operated - no more overages or shortages.
