A change that keeps things flowing

From repeat diaphragm failures to reliable, low-maintenance filter press feed.


Challenge

Reliability decides a lot in metal recycling. When a pump on the filter press feed line goes down, the whole process stops with it. At a Belgian metal recycling site, that pump was a Josef Emmerich diaphragm pump feeding slurry to the filter press, and it kept letting the team down.

Diaphragm ruptures were a regular event, each one bringing repair costs and unplanned downtime. The slurry application caused frequent blockages, and the maintenance load kept growing. What the customer needed was a pump that could deliver high discharge pressure reliably, with minimal intervention.

Vaikon was already the site's trusted spare parts supplier for its centrifugal pumps and knew the installation well. When the diaphragm pump's problems became too costly to keep patching, that relationship made the next step an easy one.

One pump swap, no more ruptures
The diaphragm pump feeding the filter press ruptured regularly under slurry duty. The Schegler VQ1.5x1 Fasto centrifugal pump that replaced it hasn't failed once since installation.

Engineered for continuous abrasive duty
High-chrome liners, an extra heavy-duty bearing and a double mechanical seal with thermosyphon system let the pump handle abrasive slurry around the clock, without the repairs the diaphragm pump kept needing.

Maintenance down to a daily rinse
Where the diaphragm pump demanded frequent intervention, the Schegler VQ1.5x1 Fasto pump needs only an end-of-day clean to prevent sand settling in the discharge line, and a periodic check of the IBC water level.

Solution

Vaikon replaced the diaphragm pump with a Schegler VQ1.5x1 Fasto centrifugal pump, built for demanding slurry duty. Its heavy-duty construction keeps performance stable under abrasive media, year after year.


The pump carries high-chrome liners for optimal resistance to abrasion, an extra heavy-duty bearing assembly, and a double mechanical seal with pressure unit, thermosyphon system and IBC container.

That combination brings the maintenance load down to the essentials. The customer checks the IBC water level and keeps the pump lubricated, or lets Vaikon's Pulsa automatic greasing system take care of that too.








Result

Since the Schegler Fasto pump was installed, process reliability has improved noticeably. A quick clean at the end of the day, to stop sand from settling in the discharge pipe, is now the only routine task.

Diaphragm failures are gone, and so are the blockages that used to interrupt filter press feeding. Maintenance needs have dropped sharply, uptime and production availability are up, and the total cost of ownership is lower over the pump's lifetime.

More flow, less downtime: a solution built to last.
