Which type of pump is most efficient?
In general, a reciprocating pump is more efficient than a centrifugal pump.
Reciprocating machines are generally applied on low-flow/high-head service.
Centrifugal pumps can have efficiencies as low as 40 percent on low-flow/high-head service..
What are the specifications of a pump?
Specifications. Pumps are commonly rated by horsepower, volumetric flow rate, outlet pressure in metres (or feet) of head, inlet suction in suction feet (or metres) of head. The head can be simplified as the number of feet or metres the pump can raise or lower a column of water at atmospheric pressure.
What is the maximum height water can be pumped?
The atmospheric pressure would be capable of sustaining a column of water 33.9 feet in height. If a pump could produce a perfect vacuum, the maximum height to which it could lift water at sea level would be 33.9 feet, as shown in Example 1.
How do I choose a pump size?
Pump sizing can be accomplished in six steps, as follows:Find the total dynamic head, which is a function of the four key components of a pumping system, such as the one shown in Figure 1.Correct for the viscosity of the fluid being pumped, since pump charts and data are given for water with a viscosity of 1 cP.More items…•
What factors must be considered when selecting a pump to be used in a process?
The primary factors in pump selection include: definition of the technological process outline and main process parameters, such as flow, pressure and temperature; determination of the required pumping services; complete description of the fluid to be handled in each pumping operation (type of fluid, temperature, …
How do I choose a pump motor?
When choosing a motor for a centrifugal pump, you must consider the impeller size, maximum capacity, specific gravity of the fluid, and service application in case API requirements apply. If you take these things into account, you will select the right motor for your centrifugal pump application.
How far can a 1 hp pump push water?
about 25 feetYou can’t suck the water up more than about 25 feet, but once you get the pump behind the water you can push it virtually forever.
How much HP pump do I need?
Horsepower theoretically required for pumping water equals the gallons per minute multiplied by the head in feet, and divided by 4.000 For power recommended, divide by 2000 instead of 4000.
What is capacity of a pump?
The capacity of a pump has two components, the pump discharge rate and the discharge pressure. The discharge rate is normally measured in gallons per minute (gpm) in English units or liters per second (lps) in metric units.
How far will a 1/2 HP well pump push water?
40 ftA 1/2 Hp pump should be able to push water up hill 40 ft without problems. The distance it pumps is somewhat irrelevant. The more important question is how deep the well is. If the well is shallow then a pump is able to suck water up the well pipe.
How many feet can a pump pull water?
For every foot that you pull the water you will lose . 5 psi. so at normal atmospheric pressure you should be able to raise the water about 28-29 feet. just learned this through a pump class for firefighting.
