Pump Products FAQs

Different jobs require different pump systems. Below are some frequently asked questions about our pump products.

What are centrifugal pumps and what are they used for?

Centrifugal pumps are mechanical devices used to transfer fluids. A centrifugal pump works by converting rotational kinetic energy into hydrodynamic energy. These pumps are commonly used in various industries for moving water, chemicals, oils, and gases. Centrifugal pumps are also the most common pump type used to transfer corrosive liquids.

What are the different types of centrifugal pumps?

There are three primary types of centrifugal pumps:

  • End suction centrifugal pumps
  • Inline centrifugal pumps
  • Self-priming centrifugal pumps

End suction centrifugal pumps are the most common type of centrifugal pump used for general applications. Inline centrifugal pumps are mostly used for heating and cooling systems. Self-priming centrifugal pumps are used in applications where the pump must be able to prime itself. To ensure you have the right pump for the right job, connect with a ProSeal specialist today.

What is a self-priming pump?

A self-priming pump is a centrifugal pump with a built-in mechanism that allows it to prime itself. This means it can start pumping without the need for manual priming. Self-priming pumps are commonly used in applications where the pump is located above the fluid level, where manual priming is difficult or impossible.

How do you prime a pump?

Priming a pump involves filling the pump and suction line with the fluid that needs to be pumped to create a vacuum. This allows the pump to start pulling and transferring the fluid. General steps to prime a pump are as follows:

  1. Fill the pump casing with the fluid to be pumped until it reaches the centerline of the impeller.
  2. Close all of the pump suction and discharge valves.
  3. Open the vent valve on the discharge line.
  4. Start the pump motor and let it run for a few seconds to release any air in the pump casing and suction line.
  5. Slowly open the suction valve until the fluid enters.
  6. Close the vent valve once the fluid is flowing smoothly.
  7. Open the discharge valve slowly until the desired flow rate is achieved.

Exact steps for priming a pump will vary depending on the specific pump design and application. Consult the manufacturer's instructions or a ProSeal pump specialist for specific instructions on how to prime your pump.

What’s the difference between multistage centrifugal pumps and single-stage centrifugal pumps?

A single-stage centrifugal pump has only one impeller and is used for applications that require low-pressure pumping. A multistage centrifugal pump has multiple impellers and can be used for high-pressure applications. Multistage pumps are more energy-efficient, but they also have higher installation and maintenance costs. Vertical multistage centrifugal pumps have a vertical shaft where the stages are stacked on top of each other. Clearances are small in these types of pumps, so they work best for clean water applications.

Positive displacement pump vs. centrifugal pump — what's the difference?

Positive displacement pumps move fluid by trapping a fixed amount of fluid and then forcing it through the pump's discharge. They are suitable for handling viscous fluids since they can operate with higher suction pressure. Centrifugal pumps, on the other hand, are better suited for lower-viscosity fluids and are more efficient at transferring larger volumes of fluid.

Positive displacement pumps such as diaphragm pumps and gear pumps are typically used in low flow rate applications, while centrifugal pumps are commonly used in situations with high flow rates.

What's the difference between a long coupled pump and a close coupled pump?

The main difference between a long coupled pump and a close coupled pump is the way the pump is connected to the motor. In a long coupled pump, the pump and motor are separate units connected by a coupling. The coupling allows some flexibility between the pump and motor for easier alignment adjustments during installation. In contrast, a close coupled pump has the pump and motor directly connected, with no coupling in between. The pump and motor are often mounted on a common base, making the unit more compact and easier to install.

Close coupled pumps are often used in applications where space is limited and ease of installation is important. Long coupled pumps are typically used in applications where alignment flexibility is necessary or where maintenance and repair are a greater priority.

More key differences between long coupled pumps and close coupled pumps:

  • Maintenance: Long coupled pumps are typically easier to maintain because the pump and motor can be separated for maintenance or repair. Close coupled pumps can be more difficult to maintain because the pump and motor are integrated, making it harder to access the components.
  • Efficiency: Close coupled pumps tend to be more efficient than long coupled pumps because there is less energy loss due to the absence of a coupling.
  • Cost: Close coupled pumps are generally less expensive than long coupled pumps because they require fewer components.
What causes shaft deflection?

Shaft deflection in a pump system refers to the displacement of the pump shaft from its original position due to external forces acting on the system. Common causes of shaft deflection include:

  • Misalignment
  • Imbalance
  • Vibration
  • Thermal expansion

When a pump shaft experiences deflection, it can cause problems such as increased wear and tear on the bearings, decreased pump efficiency, and even catastrophic failure. Shaft deflection can also cause mechanical seal failure, resulting in leakage and contamination of the pumped fluid.

To prevent shaft deflection in pump systems, it's important to ensure proper installation and alignment of the pump and motor and to regularly monitor the system for any signs of vibration or imbalance. In addition, selecting the appropriate pump design and materials can help minimize the effects of external forces on the system. Speak with a ProSeal pump specialist today for more expert guidance.

What size submersible pump do I need?

The correct size of a submersible pump depends on the volume of fluid you need to move and the height the fluid needs to be lifted. To determine the appropriate pump size, you will need to know the total head, fluid flow rate, and pipe size. Consult with a ProSeal pump specialist to determine the appropriate pump size and type of pump for your application. We distribute, install, and repair a wide variety of pump types for use in multiple industries.
