Frank Flierman of contracting company Flierman bought his first Double Twin Shift slurry tanker three years ago. After good experiences and an interesting residual value, Frank decided to trade in the ‘old’ Double Twin Shift for a new one.
“… and with affordable tyres underneath that you can also buy half-worn”
A big spearhead when choosing the new slurry tanker was the tyres. Tyres of a common size are used under the Double Twin Shift. As a result, there are relatively many used tyres available in the market that fit under the Double Twin Shift.
” We have driven away about 90,000 m3 with that and I haven’t looked back at the rotary lobe pump at all. “
The slurry route of a rotary lobe pump is pretty much the same on all KAWECO slurry tankers. The rotary lobe pump is always placed centrally and as low to the ground as possible. Due to the central positioning, the number of bends is minimal, optimising capacity. To protect the rotary lobe pump from unwanted objects, it is advisable to fit a cutting device (KAWECO Maxi Cut). This can be found on the right side of the tank, i.e. before slurry passes through the rotary lobe pump. This results in a significantly longer life of the rotary lobe pump. Loonbedrijf Flierman is a good example of this. The company has applied over 90,000 m3 of slurry with their first Double Twin Shift slurry tanker without having to perform any maintenance on the pump.
“I find that with the new tank I can guarantee that to the customers well. “
Frank also points out that it is important for him to have a clear picture of the costs and to be operationally secure. Especially since they spread quite a few cubic metres of slurry with just one tanker. Partly due to the service from the dealership, Frank thinks he can guarantee this to his customers with the new tank.
