Another significant benefit of GRP water tanks is their insulation properties. The structure of GRP helps in maintaining a stable water temperature, which is essential in preventing algae growth and ensuring the water remains clean and safe for consumption. This aspect is especially beneficial for agricultural applications, where irrigation systems require controlled water temperatures to promote healthy crop growth.

Runout must be kept to a minimum. Movement of the center of rotation is usually caused by bearing wobble or shaft whip. When coupled with misalignment, this problem is compounded. Contrary to popular belief and common practice, the installation of flexible couplings cannot correct or compensate for misalignment.

In this way, selecting the appropriate oil seal will lead to machine design that is economically superior!

Silicone (VMQ) Oil Seals

Figure 4 shows the features of a JTEKT oil seal.
Which option is best? This decision is left entirely to you. Whatever solution you choose, the seal needs a proper fit to function.
Nitrile (NBR) Oil Seals
Before installing the oil seal, it is important to lubricate it to reduce friction and prevent damage during installation. A silicone-based lubricant is recommended for most applications. If the oil seal is to be installed in a high-temperature or high-pressure environment, a more specialized lubricant may be required.

After the oil seal is positioned in the groove, apply even pressure to the oil seal using a seal driver or a similar tool. This will help to seat the oil seal firmly in the groove and prevent it from moving during use. Make sure to apply the pressure evenly and gently, as applying too much force can damage the oil seal or cause it to deform.
5. TYPES OF FLUID: Numerous oil seals can interact with oils, fuels, grease, water and more. However, know exactly what type of fluid the rotary shaft seal will be in contact with will ensure the longevity of the seal and the machinery.
