Other Grubbens products

Apart from pulpers, the Grubbens range also includes reject separators, deflakers, pumps, and high density cleaners.

Products

Reject separator

Reject separator

The reject separator is used at the outlet of a high consistency pulper, with the purpose of cleaning the pulp from impurities. The processed pulp is pumped through a screen plate and the separated reject is dumped at batch-wise intervals.

High density cleaner

High density cleaner

The high density cleaner removes unwanted particles from the suspension using the vortex separation principle. Parts that have a higher density than the pulp - such as screws, nails, staples, steel parts, stones and pebbles - are separated, and gathered in the reject chamber.

Deflaker

Deflaker

A deflaker is used for separation of fibers in broke systems, virgin pulp systems and waste handling. Even wet strength paper qualities can be deflaked. The pulp passes through eight vibration zones under continuous flow reversals.

Booster pump

Booster pump

Grubbens centrifugal pumps are specially designed for transportation of liquids with variable consistency, or liquids containing air bubbles and lumps. Stock concentration up to 8% can be pumped with no feed pressure. With feed pressure it can manage to pump up to 12%.
