A customer in the agricultural industry approached us to streamline their egg waste protocol, as their current method was time-consuming.
Tapflo UK supplied a hopper-fed progressive cavity pump solution to provide reliable transfer of high-viscosity materials in a demanding application. The system was designed to handle challenging products with consistent flow, while the hopper-fed configuration enabled efficient feeding and reduced processing issues.
Our Solution
We suggested a Hopper Fed Progressive Cavity Pump that would be fitted with the client’s own fabricated hopper. This removed some of the cost elements for the client, as they have their own fabrication workshop.
The pump was selected in painted steel because it’s used to pump waste eggs that are not intended for human consumption; therefore, the client didn’t require a sanitary execution. It was also fitted onto a trolley for easy mobility when required, so that the operators could move the system to the required location, rather than carrying heavy buckets to the pump, thereby reducing some of the manual labour.
An inverter was fitted onto a steel plate against the trolley, allowing the on-site operators to speed the pump up during peak production (where more eggs fall off the conveyor line), or slow down when production is quieter.
A remote controller with a 2m cable was also supplied to control the inverter from a slightly greater distance and to prevent bending down to adjust its speed, given its low profile.
Overall, the Progressive Cavity Pump System was as compact as possible, reducing the space required on-site for the mobile pumping solution, and proved to be as cost-efficient as possible whilst still retaining the necessary features required with the highest build quality. The pump was supplied by our partners in Italy, Nova Rotors.
