Beyond the Limits of Flowability: The New Drum Emptying System with Follower Plate

Even high viscosity pumps come to their application limits very fast, when trying to pump highly viscous, non-flowable substances. The newly developed drum emptying system with follower plate from Lutz Pumpen exceeds these limits and the infinitely variable operation enables particularly gentle pumping of pastes and non-flowable substances in the food, pharmaceutical and industrial sectors.

The complete system is supplied on a mobile trolley, which ensures maximum mobility and flexibility. The ergonomic design simplifies the operation for the user. A simple and convenient control system enables the commissioning.

The manual, infinitely variable control of the FDA-compliant hydraulics gently deposits the follower plate on the medium. The conveying speed is infinitely variable and the containers are emptied almost pulsation-free.

Sealing lips made of EPDM (also available in FKM or PTFE) adapt perfectly to the container. Due to the pressureless guidance, the pumped medium is not pressed out at the wall. Only a small amount remains in the container after emptying which is both cost-effective and environmentally friendly.

An integrated sensor ensures that the pump is protected against dry running. Cylindrical drums, but also slightly conical containers, with or without drum inliner, can be emptied.
Adjustable drum retaining clamps secure the containers from the outside when the follower plate is removed. This is additionally supported by the application of compressed air.

To ensure fast and cost-effective cleaning, the plate and pump tube can be disassembled quickly by using Tri-Clamp connections. Generally, the follower plate is operated with a 3A-approved free of bacteria traps and thread-free pump. The mobile trolley, the hydraulic unit and the follower plate are also made of polished stainless steel.

Depending on the pump size and the drive motors that can be combined with it, flow rates of up to 120 l/min can be achieved. The range of drive options extends from standard three-phase motors with frequency converter to compressed air motors and gear motors.

When retracted, the total height of the system is only 2.12 m and is therefore ideally suited for low ceiling heights and transport in elevators. The weight of the mobile unit, without pump, is approx. 140 kg. In order to cover the largest possible range of tasks, the system can also be used without the follower plate as a pure, mobile lifting stand together with the pump.

The follower plate system can be used to pump highly viscous, pasty and viscous substances which are not capable to flow. Examples from the various application fields are lipsticks, mascara, ice cream, tomato paste, infant food, ointments, fats and colours.
