MINIMUM AND MAXIMUM GREASE LEVEL INDICATORS
The standard grease pumps have two level types:
Minimum capacitive level (for 10 and 30 Kg tanks);
Max visible level (floating).
You can install a laser level type as alternative.
Minimum and maximum level are
floating switch type
in oil version.
5.2.1 MINIMUM CAPACITIVE LEVEL (GREASE)
The minimum level is realised by a capacitive probe that is positioned at the end of a tube mounted on the tank cover. When the
minimum level is reached, the probe signals that the lubricant is low. If the capacitive probe is replaced, the capacitive probe
must be recalibrated (see calibration procedure – CHAP. 7.2. User instructions).
5.2.2 MAX LEVEL WITH MICRO-SWITCH (GREASE)
The phase that the lubricant is loaded in the tank is realised by the operator, who uses a pump.
Once the maximum lubricant level is reached, a rod is activated that indicates that the tank is full.
5.2.3 LASER-LEVEL (OIL AND GREASE)
Inside the Ex d kit case there is a laser range sensor with connector.
It has a 4-digit alphanumeric display and a reading distance up to 10 Mt.
The device includes the programming buttons.
5.2.4
MINIMUM AND MAXIMUM LEVEL WITH A FLOAT
(OIL)
The level is made with two floats at the ends of metal shaft. Lower float acts as a minimum level by closing a contact when the
low position is reached. The Upper floats acts as a maximum level by closing another contact at high position.
5.3
SPATULA FOR GREASE
Two tanks have been foreseen with capacities of 10 and 30 kg. (22 – 66.1 Lb) two for oil and two for grease.
The tanks are supplied standard with a spatula and a scraper, which must not be disassembled during their assembly or
replacement. Under the spatula, there is a standard electrogalvanised steel mesh with 0.5 mm holes (0.02 in.). The pump is
protected from possible foreign bodies that could be inadvertently present while the tank is being loaded.
5.4 PRESSURE GAUGE
The pressure gauge is glycerine type, so as protect it from any pressure spikes that may create damage. It is assembled directly
in the manifold group (placed in front of the pump).
5.5 BY-PASS
Pressure gauge is pre-calibrated to 300 bar but it can be adjustable from 0 to 380 bar.
5.6 ELECTRICAL CONNECTIONS
On the structure of the base is possible to mount a safety terminal box that contains a terminal board to connect the electrical
components of the Mini-SUMO Atex assembly (Motor, valves, level indicators, etc).
Choosing this option the pump will be supplied with wirings already connected to the terminal strip.
