– Zinc-plated exposed pump surface
– High quality of back-up ring standard
– Hardened key components in hand pump
The hand hydraulic pump creates pressure by pulling and pushing the handle manually. The zinc plate on the surface prevents rust in moist working surroundings and the hardened seat of the ball reduces the degree of wear in repeated hydraulic oil shock.
Finotek hydraulic hand pump design makes it much operation reliability and manufacturers hydraulic hand pump as per 7/8″-14UNF-2A, or 3/4″-16UNF threaded port cavity industrial standard, and strictly testing will guarantee pump high performance and no need regular maintenance at installation in the system, saving much labor cost for service it.
With compact pump design, hand pump is much rapid and easily assembled into many sorts of hydraulic blocks as power sources. There is a two layer O-ring inside to pump around the movement piston, which is making the pump without inner leakage and quick pressure rising while push and pull the handle. Finotek hydraulic hand pump uses mineral oil as medium, the oil pressure of the pump will be able to reach max. 40Mpa for a certain time. The small and without electric power units is better to choose this kind of pump as power source, for its little cost and saving more working space, especial eliminating the piping connection and advantage of rapid installation in few minutes.
← Pulling – Refill stroke
The hydraulic hand pump is operated by a mechanical force pulls the pistons upwards. The pressure in the chamber beneath the piston begins to fall. The reduced pressure causes the inlet valve ① to open. The outlet valve ② remains closed because of the pressure of hydraulic oil in the outlet pipe. Fluid oil enters the chamber and fills the space beneath the piston.
Pushing – Compression stroke →
When a mechanical force pushes the piston of hydraulic hand pump downwards, the pressure beneath the piston begins to rise. This cause the inlet valve ① to close. The valve housing now traps the fluid oil because it cannot escape back through the inlet valve ①. When the pressure is sufficiently high the outlet valve opens. The high pressure oil is forced up the outlet pipeline or tube. Hydraulic oil continues to flow up the pipe until the piston reaches its lowest point. The cycle starts again.
Note Of Hydraulic Hand Pump Before Operation:
Note: From the description above, the normal operation of the pump requires the oil in the outlet pipe being full, when the pump is in first operation, there is no oil in the outlet pipe of hydraulic hand pump, this is the reason why to pull and push in 3-5 times without any pressure before the working. A good quality hand pump is easy to pressurize for its excellent sealing performance, otherwise, it is hard to make the hydraulic hand pump to start working.
Advantage of Hydraulic Hand Pump By Finotek
1. Two disc cylinder grade of O rings as sealing element in hydraulic hand pump: Double layer sealing made from nitrile rubber materials, for high pressure operation. The material we chosen is first class grade with super anti wear, flexible softness characteristics for easy handle operation and excellent sealing in high pressure.
2. The inner surface (house chamber) of hydraulic hand pump is manufactured by high precision digital machine to smooth the fluid flow in its chamber, maintaining steady flow rate in each pulling or pushing operation.
3. The outer surface of piston has fine milled before assembly, the precise and smooth surface is keeping the good sealing while the oil in its chamber, making the hand level is easily working, preventing tuck phenomenon and largely advance the service life of hydraulic hand pump.
4. The frame of hydraulic hand pump is made from casting iron with strong structure against loner-term force and bearing sudden impact. It is created by model as per our design drawings, therefore, the customized design of frame is available to us, please contact us for specific dimensions.
5. The hydraulic hand pump is made of carbon steel with harden treatment, high precision digital machines to process all the dimensions. Low noise, easy operation, longer service life and the standard and customized threads are available, contact us now for your project.
