Applications of Peristaltic Hose Pumps in the Oil, Gas & Petrochemical Industries
In the oil, gas, and petrochemical industries, pumping systems operate under extremely demanding conditions — from corrosive and abrasive fluids to high pressures and variable viscosities.
Under these circumstances, the peristaltic hose pump stands out as a reliable and efficient solution due to its simple design, minimal fluid contact with mechanical parts, and ability to run dry or semi-dry without damage.
Pars Hesgar Paj manufactures peristaltic hose pumps engineered for precise chemical dosing, transfer of viscous or abrasive fluids, and safe handling of aggressive or flammable materials. The durable hoses used in these pumps are resistant to hydrocarbons, acids, alkalis, and a wide range of industrial chemicals.
Key Applications in Oil & Gas Operations
- Chemical injection and additive dosing, including corrosion inhibitors, antiscalants, and line-cleaning chemicals
- Transfer of abrasive slurries and solid-laden fluids, such as drilling mud, refinery sludge, and tank residues
- Accurate dosing of catalysts and treatment chemicals in refining and petrochemical processes
- Pumping of corrosive or viscous liquids without valves or complex sealing systems
- Leak-free transfer of hazardous or high-value fluids, as the medium only contacts the inner surface of the hose
These pumps offer exceptional reliability, abrasion resistance, and low maintenance, making them ideal for chemical injection systems, refinery applications, sludge transfer, and on-site oilfield operations.
Explosion-Proof Capabilities (ATEX / IECEx)
Pars Hesgar Paj designs and supplies explosion-proof (Ex-proof) peristaltic hose pumps for hazardous area applications.
These versions comply with ATEX and IECEx standards, ensuring safe operation in environments where flammable gases, vapors, or explosive dust may be present, including oil, gas, petrochemical, mining, and chemical processing facilities.
Features and Advantages
- Explosion-proof enclosures and certified components: Motors and control panels can be supplied with Ex-d or Ex-e protection, suitable for different hazardous Zones (Zone 1, Zone 2, etc.).
- Advanced electrical protection: IP66/67-rated enclosures, secure electrical circuits, and anti-spark protection systems.
- Antistatic and conductive hoses: Prevent static charge buildup when transferring flammable fluids; hose material is selected based on chemical compatibility, abrasion resistance, and conductivity.
- Non-electric drive options: Pneumatic or hydraulic drives available for extremely hazardous or remote areas where electrical power is restricted.
- Safe monitoring and control systems: Explosion-proof sensors for pressure, leakage, and hose integrity; optional remote monitoring and control integration.
Typical Explosion-Proof Applications
- Chemical injection of hazardous materials in refineries and oil pipelines
- Slurry and drilling mud transfer near offshore platforms or explosive environments
- Dosing of chemical additives in petrochemical plants where flammable gases are present
Selection and Safe Operation Guidelines
- Define Zone and hazard type: Identify the Zone classification (e.g., Zone 0/1/2 or 20/21/22) and the nature of the explosive gas or dust before selecting the pump model.
- Hose compatibility: Verify hose materials for chemical resistance, abrasion strength, and electrical conductivity.
- Certification and compliance: Pumps can be supplied with ATEX or IECEx certificates and appropriate IP ratings upon request.
- Maintenance and inspection: Regular visual inspection and trained operation are essential for long-term safety in Ex-rated environments.
