A Pumping & Mechanical Seal Company with Over Three Decades of Experience

A self priming pump is a liquid pump that already has liquid stored in the system for the pumping process. They are most often found in process plants, as the start-up liquid already in the pump increases efficiency. Self priming pumps are suitable for any industrial process that requires repeated operations.

To select the pump size needed, you'll need to determine the gallons of water per minute during peak periods. It's essential to use the peak time rather than the average. If using the average, your submersible pump will not function properly during those peak times of the day. Our team at ProSeal Service Group can help you determine what size is necessary. Call us for more information.

There are two main classifications of pumps: dynamic and positive displacement. Dynamic pumps put velocity in the liquid using a rotating element to move the liquid throughout the pump. The most commonly known type of dynamic pump is a centrifugal pump. Positive displacement pumps use pressure by trapping the fluid into a fixed volume before pushing it out the discharge pipe.

Centrifugal pumps are the most common pump used today. They are dynamic pumps, so they use rotational energy generated by impellers to transfer liquid throughout the system. They are inexpensive and have a relatively simple pump, which also helps their popularity.

If you need a mechanical seal repair, the most common cause is improper installation, which is why it's vital to buy reliable mechanical seal products installed by professionals.. Other common causes of mechanical seal failure include contamination from debris, typical wear and tear, and chemical corrosion. Whatever the reason, ProSeal Service offers mechanical seal repair services to get your business back on track quickly.

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.

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.

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.

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 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.

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.

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.

High-quality lubricants include lubricating oils, synthetic fluids, and greases designed to reduce friction and wear in heavy-duty machinery. They protect against damage, enhance performance under high temperatures, and extend equipment life, minimizing downtime and costs.

Heavy-duty equipment requires lubricants like:

• Lubricating oils for general use.
• Engine oils and motor oils for high-performance engines.
• Grease for components like gears.
• Water-based lubricants for cooling and eco-friendly applications.
• Full synthetic fluids for high temperatures and durability.

Lubricants, including synthetic and high-quality water-based options, form a protective film between moving parts. This reduces friction and wear, prevents overheating, and ensures smoother operation, especially in heavy-duty and high-temperature environments.

Full synthetic lubricants, such as engine oils and motor oils, handle high temperatures better, reduce wear more effectively, and resist sludge buildup. They last longer and perform consistently in heavy-duty applications, offering superior protection and efficiency.

Water-based lubricants are ideal when cooling and eco-friendliness are priorities. They reduce friction and wear in high-temperature applications and are commonly used where biodegradability is required, though less suited for extreme heavy-duty tasks.
