In the hose-peristaltic pumps manufactured by Pars Hesgar Paj, lubrication plays a vital role in reducing friction, controlling temperature, and ensuring stable pump operation. The lubrication system is engineered to work in full harmony with the hose structure, compression mechanism, and operating conditions.
Importance of Lubrication
A proper lubricant in a hose-peristaltic pump performs three key functions:
- Reduces friction between the hose and the shoes/rollers, extending hose life
- Dissipates heat generated during hose compression and prevents overheating
- Maintains correct contact pressure, preventing flow reduction or back-flow
Guidelines for Selecting and Using Lubricants
- Chemical Compatibility:The chosen lubricant must be fully compatible with the process fluid. Incompatibility may lead to hose damage or unwanted chemical reactions.
- Correct Lubricant Level: An insufficient lubricant level can cause excessive temperature rise, accelerated wear, and unexpected pump shutdowns.
- Scheduled Lubricant Replacement: Lubricant must be replaced after every hose replacement and periodically depending on operating hours and process conditions.
- Pre-lubrication of New Hoses: Before installing a new hose, its outer surface must be completely coated with lubricant to ensure smooth installation and uniform compression.
Lubrication Requirements Across Different Industries
Hose-peristaltic pumps are used in a wide range of industries, and each industry requires a different lubrication approach:
- Mining & Mineral Processing: Abrasive slurries and heavy-duty conditions require robust lubricants and precise temperature monitoring.
- Chemical Industry: High fluid reactivity demands chemically neutral and fully compatible lubricants.
- Food & Beverage: Only odorless, non-toxic, food-grade lubricants are acceptable.
- Petrochemical / Oil & Gas: Continuous processes and high temperatures require thermally stable lubricants.
- Water & Wastewater Treatment: Thick sludge and dosing chemicals need lubricants with effective heat dissipation and long-term stability.
Critical Warning
Technical Evaluation Is Essential
Lubricant selection for hose-peristaltic pumps is never universal. Each industry, fluid type, and operating condition requires specific technical evaluation. Incorrect lubricant selection may:
- Cause severe temperature rise in the pump
- Lead to rapid hose failure
- Result in complete system shutdown
- Create significant operational damage
- And in sensitive industries (such as food or reactive chemicals), it may even be catastrophic
For these reasons, Pars Hesgar Paj strongly recommends that fluid specifications and installation conditions be reviewed by our technical team before selecting any lubricant.
