Fluids with low to medium viscosity at a distance of about 150 ft. would best be pumped using a 3:1 air piston pump. ... For example, a popular ratio piston pump for auto shop grease is 50:1.Aug 3, 2018
How do you calculate pump pressure?
In simple terms, the mathematical constant 2.31 converts a unit of energy against gravity into a unit of force against any other area. This constant converts a foot of head of water into pressure: Head in feet of water divided by 2.31 equals pressure in psi, and pressure in psi times 2.31 equals head in feet.Oct 13, 2010
What is pump head pressure?
Head pressure is a specific type of pressure used in pump systems. It is a measurement of the height difference between the fluid being moved and the discharge point. For example, let's say you have a well of water that is 2 metres underground, and you have a tap and pipe system half a metre above ground.
What does pump ratio mean?
It can mean a motor and a pump together as a pump package or refer to the fluid displacement pump. ... The pump ratio is the relationship between the effective area of the air or hydraulic motor's piston and the effective area of the pump's piston.
What does 10 1 pump mean?
Typically, a 10:1 air motor/pump combination is equivalent to a 1:1 hydraulic motor/pump combination because typical hydraulic pressure is 1000 psi (70 bar) and typical air pressure is 100 psi (7 bar). In this example, both the air powered and hydraulic systems have an identical pump.
How does a pneumatic grease pump work?
Air-powered or pneumatic grease guns use compressed air to apply pressure to an air piston, which drives the grease piston and forces lubricant out of the coupler into a grease fitting. By depressing the gun's trigger, a steady flow of lubricant is dispensed. Typically, pneumatic grease guns are rated up to 6,000 psi.
What are the different types of oil pump?

What are the three 3 types of oil pumps used in automatic transmissions?
- Gear Pump. Gear pumps operate on the water wheel principle. ...
- Rotary Pump. The basic principle of the rotary pump is the same as in a gear pump. ...
- Crescent Pump. The crescent pump is advantageous in situations where high delivery rate of oil is required, particularly at low engine speeds.
What type of pump is an oil pump?
Centrifugal pumps are the most common types of pumps used in the oil and gas industry. Centrifugal pumps use centrifugal force through the rotation of the pump impeller to draw fluid into the intake of the pump and force it through the discharge section via centrifugal force.Jun 25, 2019
What is a oil pump in an engine?
The oil pump provides the force that delivers oil through galleries and passages around the engine. Oil pumps are usually either inside the oil pan and driven by a camshaft or outside the pan and driven by a crankshaft.
What are the 3 types of oil pumps?
- Rotor oil pump. A rotor type of oil pump is also called a gerotor pump. It contains an inner gear that turns inside the outer rotor. ...
- Twin Gear Pump. The twin gear pump is also known as an external pump. ...
- Front cover oil pump. The front cover oil pump is also known as an internal or external pump.
What type of pump is used in an automatic transmission?
Abstract In order to improve the hydraulic efficiency, modern automatic transmissions tend to apply electric oil pump in their hydraulic system. The electric oil pump can support the mechanical oil pump for cooling, lubrication, and maintaining the line pressure at low engine speeds.
