Filling Corrosive Liquids with Trigger Pumps and Refill Caps
Project Description
The Filler-Capper Monoblock BR16/8/165 is one of the most versatile filling and capping machine bases designed by Mengibar.
It operates at 100–150 upm with an OEE > 98%. In this case study, we analyze how Mengibar customized this standard base to handle highly corrosive liquids.
The Challenge
Once again, we were required to install a Monoblock in a room exposed to corrosive fumes from nearby lines, and also to fill corrosive products. Therefore, a special construction was needed to protect the machine both inside and out.
How did Mengibar solve it?
In addition to our standard corrosion protection—using special materials such as Hastelloy and PA11/Halar coating on all stainless-steel components (remember, Mengibar does not use plastic frames)—we paid special attention to machine ventilation and fumes detection.
- The Filling Carousel features an overpressurized enclosure with top/bottom plates and cover made of AISI-316L stainless steel + PA11 coating.
- The Capping Carousel also includes an overpressurized enclosure with top/bottom plates and cover in AISI-316L + PA11 coating.
- The central column is built from AISI-316L, and the lower section is protected with polypropylene
Due to the highly corrosive nature of the product, a ventilation system was prepared with air infeed and outfeed flanges, to be connected by the customer to a suitable extraction system:
- Air Infeed flow in Filling carousel: 74 m3/h.
- Air Infeed flow in Capping Carousel: 74 m3/h.
- Air infeed flow in Machine base: 256 m3/h
- Air extraction from machine safety guarding: 1.655 m3/h
