Cartridge housings type “4”

The cartridge housings type “4” are robust stainless steel cartridge housings which can hold one single filter cartridge. These filter housings are modular, so the small number of basic types can be combined with individual components and options to create a large variety of application options. The use of stainless steel makes these cartridge housings not only ideal for filtering water.

Description

General information/manufacturer Putsch®

The cartridge housings type “4” consist of two stainless steel parts: a head and a sump. The intake and outlet (internal thread) for the piping is located at the head. The head also houses the seating (cutting edge sealing) for the filter cartridge, the sealing O-ring and a sturdy external thread for the sleeve nut for screwing on the sump.

The head is available in two stainless steel versions – as a cast part or as a milled part from the lathe (“mechanical worked head”). The heads are interchangeable as they are compatible with all screw-on components.

The sump for 93/4” long or 191/2” long filter cartridges acts as the housing cover and is screwed onto the head finger-tight, then tightened slightly with a special housing wrench to ensure the housing is sealed and no liquid can emerge.

As a standard, the edges of the sumps are crimped outwards. The maximum operating pressure for these cartridge housings is 10 bar. Alternatively, sumps up to max. 40 bar are available, where the sleeve nut is welded on to easily resist the higher pressure.

With the corresponding internal pressure, unintentional opening of the cartridge housing during operation is not possible.

Housing closure

The sleeve nut is used to attach the sump to the head. Depending on the requirements and the area of application, two sleeve nuts (cast or turned) are available which are compatible with all heads and sumps. Sealing is provided by an O-ring between the sump and the sealing groove in the head.

Heads, sumps and sleeve nuts are interchangeable. The range is very flexible, but thanks to the modular design it can be limited to a few basic types of heads and sumps.

Feet/installation/mounting

The cartridge housings are mounted in the pipe with the sump facing downwards. Special feet are not required. During filling, the air bubble rises to the head. The head has 1/8″ holes with bungs on the intake and outlet side for venting.

For mounting, holes are provided in both sides of the head, parallel to the pipe, intended for attaching the fixing brackets (optional).

Connections

Depending on the head, two internal threads with 3/4″ or 1″ intake and outlet are available.

The sump is available in two options: with or without 3/8″ sleeve for the drain plug.

The convenient drain plug can be released so the the cartridge housing can be drained before opening, e.g. for replacing the filter cartridge.

The 1/8″ holes in the head can be used to attach, e.g., vent valves or pressure gages.

Adapters for filter cartridges

The filter cartridges type “4” are suitable for filter cartridges open at both ends with the adapters DOE or P0.

Different options are available for seating the filter cartridges:

Variant I

The filter cartridge is guided over the fixed center bar during installation and sealed with the pressure net (removal is carried out in reverse order). The prerequisite for this variant is that the sump can be removed downwards by the length of the filter cartridge. The filter cartridge is reliably seated and centered and the operator can ensure the correct position during installation.

Variant II

If the space underneath the cartridge housing is limited, the original form is normally used. The loose sealing cap is placed in the sump and the filter cartridge is placed on the cap. The sump with the filter cartridge is guided under the head from the side and pressed on the head.

Variant III

A combination of the two previous variants: A guide bar with a welded-on sealing cap is pushed into the filter cartridge and placed into the sump with the sealing cap facing downwards. The sump can also be guided under the head from the side and pressed down. The guide rod slightly protrudes beyond the edge of the filter cartridge so that the cartridge can be placed into the head accurately.

All three variants can also be retrofitted through conversion with the relevant components. This means that customers do not have to make a final decision on the best option at the time of purchase and can carry out tests if necessary.

Once the respective sump has been selected, all filter cartridges with both ends open (DOE, P0) and a length of 9 3/4″ or 19 1/2″ will fit into the cartridge housing type “4”.
