The finger paints require pumping from various containers, e.g. buckets, lidded pails, drums or IBCs, via an existing pipe system, or through hoses, into a processing plant.

Finger paints are fairly thick to paste-like and sometimes thixotropic. These media do not flow into a pump freely.
Since our self-priming air-operated diaphragm pumps with compressed air motor can also draw in and pump viscous media, these are ideal for use in this scenario, especially the injection moulded version from our FDM series. 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 in this case, via a pipe and/or hose system.
Since the viscosity of the medium strongly increases the counter-pressure with small diameters, which then often renders cost-effective pumping impossible, a minimum pipe diameter of 1" is absolutely imperative for the finger paints. Therefore, the FDM 25 type air-operated diaphragm pump.
The feed pressure is almost as high as the air pressure created at the motor. Up to 8 bars are possible. The paints are only subjected to minimal shear forces which makes very gentle pumping possible.
Pulsations, in other words uneven medium flow, can optionally be balanced out with a pulsation damper.
Our FDM air-operated diaphragm pump can be switched on and off by opening and closing the compressed air supply. Alternatively, with a valve that simply closes the pipe/hose system at the pump end. In this scenario the air-operated diaphragm pump simply stops.
This means that the flow rate can be stopped and restarted at the pipe or hose end by closing and opening the valve. Operating personnel are therefore able to work a certain distance away from the pump.
