Hydraulic hand pump
NTN-SNR
These high-pressure pumps are designed for use with automatic return hydraulic nuts or for the mounting and dismounting of bearings coated with an oil fi lm.
Pumps are supplied as standard with the following accessories designed for use at 700 bar:
* 1 pressure gauge, minimising the risk of overloading
* 1 high-quality fl exible hose (1.5 m for a 0.3 litre pump reservoir, 3 m for a 0.9 litre reservoir)
* 1 quick coupling connection (female) suitable for NTN-SNR hydraulic nuts
* They are supplied fi lled with hydraulic oil
ADVANTAGES
* Ultra-light, compact design
* Robust reservoir in composite materials
* Ergonomic: locking of the lever to facilitate transport
* Robust: pump guaranteed for life under normal conditions of use
* Efficient: savings in time and effort due to the two stages which allow a reduction of 80% in the number of pump strokes required in comparison with single-stage pumps.
* User safety: electrically isolated lever and safety relief valve
* Flexible: Two available reservoir sizes: 0.3 litre for HMV 54 E BF nuts and below / 0.9 litre for HMV 92 E BF nuts and below
Technical characteristics of the hydraulic oil : Contains corrosion inhibitors which do not attack sealing materials such as nitrile.
