My door slam to hard.
A hydraulic door closer would be the best choice for a door that is used by children, because it has an adjustable speed that allows you to chose how fast or slow you want the door to close, thus giving adequate time to remove little fingers and hands.
This closer has a very short delay time of less than 3 seconds.
No it does not have a hydraulic pump, oil is forced through an adjustable aperture, it is the rate at which the oil flows through this hole that has a direct affect on the doors closing speed.
the terminology of door check and door closer are from long ago, in 1880's and 1890's door closers were just a spring device to pull the door shut but not really control the closing speed or force, door check, that was more of a hydraulic or pneumatic cylinder with a piston inside (think of a regular screen door closer, but without the spring) was used together with a door spring to create some controlled door closing, and prevention od door slamming. now, the term of door check is faded because after the rack and pinion hydraulic closer was invented, the dampening effect was added onto the device in the manufacturing process. hence now they are all referred to as door CLOSER. hope this helps, expert in closers here

A big component of hydraulic pump repair is replacing worn out or damaged parts. If you can get aftermarket parts, that would significantly reduce the cost of your hydraulic pump repair.
I used Nova's hydraulic pump repair service. They were very fast and very efficient. We went with Wooster Hydrostatics for our hydraulic pump repair. Their prices were better than anyone around and they did great work.
