Robust construction with proved long life.
Pumps supply 4.5 gr. lubricant per stroke and can overcome a maximum back pressure of 350 bar.The lubricant supply takes place during the downwards stroke of the operating lever.
To set lever into its non-operating position, i.e. downwards, to avoid lubricant escaping from the pump, rotate the knurled knob of the needle valve in an anticlockwise direction.
