Soft Starter and It’s role in a Pump Control Panel
Soft starters are devices that are used to control the starting and stopping of electric motors. They are widely used in a variety of applications, including pumps, compressors, and fans, among others. Soft starters are different from variable frequency drives (VFDs) in that they only control the starting and stopping of the motor, whereas VFDs can also control the speed of the motor.
One of the primary advantages of using a soft starter over a VFD is that soft starters are often more cost-effective. They are also simpler to install and require less maintenance than VFDs, making them an ideal choice for applications where precise speed control is not required.
When it comes to controlling water pumps, soft starters are often the preferred option due to their ability to reduce the initial current surge that occurs when the motor is started. This current surge can cause damage to the motor and other electrical components, and can also result in high energy consumption. By reducing the current surge, soft starters can help extend the life of the motor and reduce energy costs.
If you are currently using a control panel that does not have a soft starter, it is highly recommended that you upgrade to one. By doing so, you can enjoy a number of benefits, including reduced energy consumption, increased motor life, and improved system reliability. Additionally, many soft starters come with built-in protections that can help prevent damage to the motor and other electrical components.
One of the advantages of using a soft starter in a control panel is that it eliminates the need for a transformer for isolation. Soft starters are designed to operate without the need for a transformer, which can simplify the control panel design and reduce the overall cost.
In traditional control panel designs, a transformer is often used to isolate the control circuit from the power circuit. This is done to protect the control circuit from high voltage or current spikes that can occur in the power circuit. However, using a transformer can add complexity to the control panel design and increase the overall cost of the system.
By using a soft starter in the control panel, you can eliminate the need for a transformer and simplify the design. Soft starters are designed to provide the necessary isolation and protection for the control circuit, without the need for a separate transformer. This can help reduce the size and cost of the control panel, while also improving the overall reliability of the system.
In addition to eliminating the need for a transformer, soft starters also offer other benefits for control panel design. They can reduce the amount of wiring required, as they typically only require a few connections to be made. They can also be easily integrated into existing control systems, making them a flexible and adaptable solution for a wide range of applications.
Overall, using a soft starter in a control panel can simplify the design, reduce costs, and improve the reliability of the system. If you are considering upgrading your control panel for a water pump or other electric motor, it’s worth considering the benefits of using a soft starter.

DIY Pump Servicing
Shown picture above is a typical house-hold water pump. It consists of the impeller section, the motor, and a pressure controller.
When there is a leak in-between the impeller section and the motor, it usually means your mechanical seal has worn out and in need of replacement.
If there is uncontrolled leakage from the pressure controller. It usually means the diaphragm of the pressure controller has reached its life cycle, and needs to be replaced.
As you can see DIY Pump Servicing is easy.

Installation of Glass Lined Mechanical Seal for Agitator
The picture above shown is the top of an agitator. While there are blades contained in the agitator. There are mechanisms that helps to turn the blades. As shown, there is a high powered motor mounted on top and coupled with the blade’s shaft. In the middle sits a glass lined mechanical seal, hugging the shaft and sealing the agitator, preventing gases from leaking outwards.
SP PAC-SEAL Installation of Glass Lined Mechanical Seal for Agitator will be described as follows.
Before starting the replacements like everything else, preparation is highly scrutinized. The correct size of mechanical seal must be ready on-site. Due to the size of this agitator, an overhead crane is necessary to proceed with maintenance or replacement works. Also for this design of agitator, two C- spanner of the correct size are required. Other tools such as an electric nut driver comes in handy.
Once preparations are done, work shall commence. The cables connecting to the electric motor are disconnected and tied away safely.
Next is the removal of coupling between shaft and electric motor. Once the coupling is removed, the electric motor shall be secured to a crane, before loosening the nuts of gearbox to the housing. The electric motor and gearbox is lifted away together and set aside.
Upon removing the motor and gearbox, the shaft shall be secured with a crane on the top end, while the bottom end of the shaft shall have soft cloth or leather to prevent the shaft from damaging the interior of the agitator. After securing both ends, the mechanical seal usually has a setting stopper to secure it before loosening for removal. Once the settings are placed back in and secured, the C-spanner is then used to open the nut locked to the shaft and supporting it at the housing.
Bare in mind, once the nut is loosen, the shaft may drop downwards. After the nut is removed, the shaft is let down slowly, until touching the bottom. The securing of shaft can then be released. Remove the housing would give much needed space to then remove the mechanical seal.
The procedure is then reversed with a new mechanical seal installed.

How to choose a Mechanical Seal face material
A Mechanical Seal face material is selected by understanding the condition the mechanical seal will be subjected to. The media/ fluid that will be in contact with the mechanical seal, and the pressure that will be exerted, influence the performance of a mechanical seal.
For example: If the viscosity of the media is high, a finer and more uniform grained structured material is required to withstand the friction during rotation which produces heat.
The most common materials for a Stationary Seal are: Ceramic , Carbon, Silicone Carbide and Tungsten Carbide. Each material has its limits weighing it with costs.
Ceramic and Carbon are the most economical material available for stationary seal, thus the most commonly used for various pumps such as hydraulic pumps, dirty water pumps, and fire fighting pumps.
Silicone Carbide is the next best choice of material for an economical yet longer lasting seal. Silicone carbide’s hardness and durability makes it a good material for use in food products, the discharge during rotation is minimal from this material.
Tungsten Carbide may be one of the highest grade of material to be used in mechanical seals. It has better durability and hardness. Best used for high temperature and to maintain media quality during operation. The drawback for tungsten carbide is the difficulty to process and higher cost for material.
Basics of Mechanical Seals
Mechanical seals are components that exists in a pump. Pumps are used to transfer media (fluid) from a location to another desired location. During the transfer of media, there are movements to assist the media in moving forward, it may be a simple fin rotating to scoop and push the media forward acting as a transferring tool. To rotate this fin there should be a force. The force may come from a manually cranked shaft or an electric motor.
In between the force provider and the transferring mechanism, media/ fluid may spill or leak to the force provider, which is not what we want. To solve this issue, a seal is needed to prevent the media from leaking and at the same time, able to provide the flexibility of rotation.
This is where the mechanical seal comes in handy.
A basic mechanical seal consists of two parts: the stationary seal and the rotating seal.
Stationary Seal has a mirror polished surface, it is then surrounded with an elastomer which acts as the sealing operation.
Rotating Seal also has a mirror polished surface, the seal has an inner elastomer which acts as the sealing operation in which it wraps itself onto a rotating shaft.
Both Rotating and Stationary Seal’s mirror polished surface are then pressed against each other, due to the smooth surfaces, the contact between surfaces are so close that fluid is unable to pass through. And because both are smooth surfaces, they are able to rotate against each other with minimal friction.
The spring that is attached to the rotating seal gives an appropriate amount of force to keep two smooth surfaces in contact. During high speed rotations the spring acts as a balancer for the rotating seal as well.
The concept of mechanical seal is then used for different medias and different situations. Some medias are corrosive, some high temperature. There are certain materials that are able to withstand a certain temperature limit before it melts.
The materials of the surface can be selected to suit different medias, which we will elaborate more in our next topic.
