5.1.1 INVERTERS
For technical characteristics and procedures for use of inverters use the product-specific manual attached to the pump.
5.1.2 POMPANTI A PORTATA FISSA
The pump is set with one or two fixed flow rate pumping elements (190 cm^3/ min for each pumping element).
The sealing between piston and pumping body is of dry type, not being provided any gasket in between.
Pumping check valve is tapered seal type. This solution ensures excellent tightness of the system at high operating pressures
(max pressure 400 bar – 5800psi).
Pumping elements are fitted on the pump body without need to disconnect piping of the line with a threaded connection which
gives an easy assembly / disassembly.
5.1.2
MAXIMUM AND MINIMUM LEVEL FOR OIL AND GREASE
5.1.3.1
Minimum laser level for grease
When the lubricant reaches minimum level, the laser probe signals the lack of lubricant. The probe has two outputs, the first NO
and the second NC when lubricant is present.
For connections and calibration see paragraph7.3.1 and 7.3.2.
5.1.3.2
Maximum/ Minimum floating level for oil
A probe rod with dual float mounted on the pump cover provides a reading of the minimum oil level (reserve) and the maximum
level (which allows the automatic refilling of the tank to be halted).
For connections see paragraph 7.3.4.
5.1.3.3
visual floating level for oil/grease
Maximum
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
ELECTRICAL CONTROL PANEL
"DROPSA" electrical control panel has been designed to provide a system complete with all the controls necessary for automatic
functioning controlled by safety signals from centralized lubrication installations. The primary voltage is 400 VAC and 50 Hz, the
other voltages are on request.
