JUDO JZA 20 - 80

Centrifugal separator

JZA 20 – 80 Centrifugal separator, for water up to 30 °C, max. operating pressure 10 bar, water flow/function range 2 – 65 m³/h.

Used in water contaminated with solids to separate solid particles via the difference in density between the substances to be separated and the water to be cleaned, as an ideal pre-treatment before backwash protective filters to extend the service life and backwash intervals.

Product benefits:

Efficient separation of solid particles

due to the difference in density between the substances to be separated and the water to be purified.
Ideal as pretreatment before backwash protective filters

to extend service life and backwash intervals
Low maintenance

no moving wear parts
Cost-saving

no sieves or other filter material
Practical

without interruption of the water supply during backwashing
Highly effecitve

due to periodic blowdown of the separated substances.
Uncomplicated

optionally with automatic blowdown unit
Simple integration into existing lines

Scope of delivery:

Centrifugal separators as compact, closed functional unit with lateral inlet and top outlet. Material Steel St. 37, painted, PN 10.

Note:

Prerequisite for the function:

Continuous flow at 70 – 100 % of the maximum flow rate.
Requires control air or control water of 5.5 – 7 bar when using the automatic purging unit.

Optional:

Stainless steel versions on request.

Expert advice required!

The typical field of application of a centrifugal separator are:

Well water with increased sand content,
as pre-filter before a water heat pump with the same problem,
sprinkler systems,
particle-contaminated circulation water.

Note: Expert advice is always required.

Yes, fill a bottle (approx. 1 liter) with the water to be tested. Now shake the bottle.

The particles, which have now settled within 2 - 3 minutes, are usually retained by a centrifugal separator.

There must be a continuous, as constant as possible, extraction for at least 10 minutes without interruption and a flow rate between 70 and 100 % of the maximum flow rate.

The centrifugal separator is not suitable for single water supply with typical intermittent domestic water withdrawal.

The water must be free of iron and manganese and have a drinking water salt content. It must not contain fibres, leaves etc. or pasty impurities (no surface water).

The water to be filtered is fed into the separator from the side so that the water rotates in the centrifugal separator. As in the chain carousel, the heavy particles are forced outwards by centrifugal forces.

Since the water is removed in the middle, there are no heavy particles left. The separated particles end up in a chamber from which they are regularly rinsed out either manually or via a timer-controlled valve.

For the separation of solid particles (above a certain size), such as sand and rust, which are significantly heavier than water (higher density).
