Denco Constant Level Oilers

1. Standard Oilers for Clean, Dry Conditions:

Model

Description

Code No.

Series N

Brass body and adaptor with 1/4" BSP

threads

12-38010

Series R

Brass body and adaptor with 1/4" API

threads

12-38011

Applications

The standard models are for use in all applications where normal atmospheric pressure exists within the plant or machinery.

2. Oilers for Use in Dirty or Wet Environments:

Model Description Code No

Series L　               Brass body and adaptor as series N             12-38120
                                 but fitted with PVC skirt to protect the
                                 breather holes.

Series P                    Brass body and adaptor fitted with PVC    12-38127
                                 skirt, no breather hole but includes an
                                 overflow tube.

Applications

Series L is extensively used in adverse environmental conditions but where normal atmospheric pressures exist.

Series P is used as a back-up device to maintain a constant level in an oil bath on equipment where the primary lubrication is oil mist or air/oil systems and where a rise in oil level would cause a problem.

3. Oilers for Sub-atmospheric Conditions:

Model Description Code No

Series Q　            Brass body and adaptor with 1/4” BSP       12-38128
                             threads. This oiler has no breather
                             holes and is fitted with an external
                             balancing tube in line with the side port.

Series S                Brass body and adaptor with 1/4” BSP     12-38129
                             threads. This valve is identical to the
                             series Q except the balance tube is at
                             90 to the side port.

Applications

Both series Q and series S models are used in applications where sub-atmospheric pressure exists in the bearing or gearbox.
If a conventional standard oiler was fitted, air at atmospheric pressure allowed in through the breather holes would force the oil out of the body. The fitting of a balancing breather tube allowboth the oiler and component to be in pressure balance.

4. Oilers for Direct Mounting:

Model

Description

Code No.

Series E

Instead of having a conventional body,
the series E constant level oiler is
designed for mounting into the
customers equipment thus avoiding
external pipework. The cap and adaptor
are made from brass and the adaptor is
threaded 1” BSP:

12-38060

Applications

This oiler can be fitted directly into the top of a sump, gearbox or bearing housing and the level adjusted to the height required.
It is ideal for maintaining a level and providing a visual indication of oil usage in very shallow and inaccessible sumps where it would be difficult to fit a standard bodied oiler at the required oil level.

Reservoirs

Reservoirs are available in glass or polythene.
