A hydraulic pump is a mechanical device transforming mechanical power to hydraulic energy. This ensures the flow of liquids, gasses and even slurries to be pumped up defying force of gravity. The pumps do not generate pressure, but creates the flow needed to develop the pressure that allows the fluid to rise through the system. There are two categories of hydraulic pumps.
Positive displacement pump: Majority of pumps use the positive displacement or Hydrostatic pump. Compared to the volumetric outflow, slippage is less for this kind of pumps. The pressure inside the pump will rise if you block the output port which will cause the pump to break down. Positive displacement can be Fixed or Variable displacement pumps. Fixed pump output will be constant in each cycle while Variable pump output can be changed by changing the geometry of the displacement chamber. There will be a comparatively low quantity and velocity of liquid involved. E.g. reciprocating pump. Willing to buyHydraulic pumps?

Non-positive displacement pump: Also called Hydrodynamic pump. There will be continuous flow because of the absence of positive internal seal, avoiding slippage. Hence, pressure top will vary causing a variable output. The velocity and quantity of liquid are large and the output pressure depends on a velocity at which liquid is made to flow. E.g. Centrifugal pump.
If you are the type of person who considers your roof as part of your landscape, then you may try out living roofs or green roofs. The green roof is a type of roofing wherein part or the whole roof is covered with a waterproofing membrane and container gardens. Here, you will be able to put some plants or vegetation that you want to have in your home. Aside from plants, you may also place roof top ponds placed on it.
Unlike most types of roof, a glass roof is usually used as a viewing platform in buildings, greenhouses and those designer roofs atop of a house. However, having them as a regular residential roof is not advisable as it allows extensive heat to permeate to your house. This type of roof is also not practical as it is tricky to repair them especially if you plan walking on it to do your roof repairs.
If you are a nature love and like to enjoy a relaxing ambiance, a thatch roof is one good type roof for your house. Especially if you are near the sea or in rural vicinity, these roofs would be advisable to have as they allow fresh air to enter.
However, if your place is prone to lightning and storms, you may rethink otherwise. Despite the fact that a thatch roof can last 40 – 50 years, depending on the materials you used for your roof, most often than not a thatch roof can burn if struck by lightning.
