When you’re ready to purchase a new pump, you must understand the key terms of pumps to make the best decision for your needs. Understanding these key terms will help you communicate more effectively with your pump supplier.
The supplier you work with will help you identify the specific type of pump needed for your application. Always work with Pumpbiz, a reputable and experienced pump supplier, to ensure you get the right pump for your needs.
Below is a comprehensive list of the key terms when buying a pump:
You must determine the required capacity or flow rate when buying a pump. The capacity is the volume of liquid that the pump can move in a given period and is typically measured in gallons per minute (GPM) or liters per minute (L/min).
The head is the energy required to move a fluid from one point to another and is typically measured in feet (ft) or meters (m).
The power rating is the amount of power required by the pump to operate and is typically measured in horsepower (hp).
The discharge pressure is the pressure at which the fluid is discharged from the pump and is typically measured in pounds per square inch (psi) or bar.
It is the temperature of the fluid being pumped and is typically measured in degrees Fahrenheit (°F) or degrees Celsius (°C).
The solids content is the amount of solid material present in the fluid being pumped and is typically measured in percent by weight (% wt).
Viscosity measures a fluid’s resistance to flow and is typically measured in centipoise (cP) or poise (P).
NPSH is the minimum net positive suction head required by the pump to operate without cavitation and is typically measured in feet (ft) or meters (m).
The efficiency measures how well the pump converts input energy into output energy and is typically measured in percent (%).”
There are many different types of pumps on the market, each designed for specific applications. When meeting with your pump supplier, discuss the particular type of pump needed for your application. Some common types of pumps include:
- Centrifugal Pumps: Centrifugal pumps are the most common type of pump and are used in a wide variety of applications. Centrifugal pumps work by using centrifugal force to create flow.
- Positive Displacement Pumps: Positive displacement pumps are designed to move fluids by trapping a fixed amount of fluid and then moving that fluid through the pump. Positive displacement pumps are often used in applications requiring a very precise flow rate.
- Reciprocating Pumps: Reciprocating pumps are designed to move fluids using a piston to create a back-and-forth motion. This type of pump is often used in applications where high pressure is required.
- Gear Pumps: These are designed to move fluids using gears to trap and move fluid through the pump. Gear pumps are often used in applications requiring a very precise flow rate.
When buying a pump, it is important to work with a reputable and experienced supplier. Be sure to discuss the specific type of pump needed for your application and understand the key terms listed above. Doing so will help ensure you purchase the right pump for your needs
