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 as it’s being used for pumping 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, as opposed to carrying heavy buckets to the pump, which has reduced 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 conveyer line), or slow down when production is quieter.
A remote controller with a 2m cable was also supplied to control the inverter when slightly further away and to prevent bending down to adjust the speed of the inverter, because of the 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.
