7 Proactive Maintenance Strategies for Positive Displacement Pumps
What is a positive displacement pump?
Positive displacement pumps transfer fluid by trapping a fixed amount and forcing it to move from the inlet to the outlet. They maintain a consistent flow rate regardless of changes in pressure or viscosity as they move fluid through a sequence of enclosed spaces. Common types include pistons, diaphragms, and rotary pumps.
Positive displacement pumps are widely used in industries such as oil and gas, chemical processing, and water treatment because they can efficiently handle viscous fluids, maintain steady flow, and operate effectively under varying conditions, ensuring reliable performance.

Are Fluorolined Positive Displacement Pumps Different?
The term “fluorolined” refers to the lining material used inside the pump, which is typically made of a fluoropolymer such as PTFE (polytetrafluoroethylene) or PVDF (polyvinylidene fluoride). Fluorolined positive displacement pumps are designed to handle corrosive fluids or liquids that may contain abrasive particles.
Fluorolined positive displacement pumps are commonly used in industries that require the handling of corrosive or abrasive fluids, such as chemical processing, pharmaceuticals, wastewater treatment, and mining.
Fluoro-lining in these pumps offers several beneficial factors. Here are a few.
Chemical resistance
Fluoropolymers like PTFE (polytetrafluoroethylene) and PVDF (polyvinylidene fluoride) offer excellent resistance to a wide range of corrosive chemicals, acids, and bases, making them suitable for handling aggressive or hazardous fluids.
Abrasion resistance
Fluoropolymers have good resistance to abrasion, which is beneficial when pumping fluids that contain solid particles or abrasive materials.
Smooth surface
Fluoropolymer linings in positive displacement pumps help to minimize friction and reduce the risk of material buildup or clogging, leading to smoother operation and longer pump life.
Key Performance Characteristics of Positive Displacement Pumps
Positive displacement pumps are crucial components in various industries due to their key performance characteristics. Let’s explore a few to understand their operation and contribution to industrial processes.
Consistent Flow Rate
Positive displacement pumps ensure a steady and consistent flow rate, despite changes in fluid discharge pressure or viscosity. Their predictable transfer nature makes them crucial in applications like chemical processing or food production.
High-Pressure Capability
Positive displacement pumps generate high pressures that pump fluids against considerable resistance or through long pipelines. They are commonly employed in oil and gas extraction, hydraulic systems, water treatment plants, and similar industries.
Viscosity Handling
These pumps are capable of handling fluids of varying viscosities, from thin liquids to viscous substances like molasses or adhesives. This versatility renders positive displacement pumps ideal for applications in industries like pharmaceuticals, paint, and food that handle thick or sticky substances.
Cavitation Resistance
Positive displacement pumps, designed to prevent cavitation, offer a steady flow, reducing the risk of damage and efficiency caused by vapor bubbles, a phenomenon that can occur with dynamic pumps.
Self-Priming Ability
Positive displacement pumps often possess self-priming capabilities, allowing them to evacuate air from the suction line and create a vacuum for fluid draw-in. This facilitates easy installation and operation, especially in situations where the pump may need to start with an empty suction line or when dealing with entrained air in the fluid.
Efficiency and Power Consumption
The ability to maintain a constant flow rate regardless of system pressure contributes to overall energy efficiency, reducing operating costs over time.
Factors to consider while selecting a Positive Displacement Pump
When selecting a positive displacement pump, several factors should be considered to ensure it meets the requirements of the intended application.
Firstly, assess the fluid properties, including viscosity, temperature, and chemical compatibility, and choose a pump that can handle the fluid effectively.
Secondly, to select the right pump with the appropriate capacity and pressure rating, consider the flow rate and pressure requirements of the system.
Additionally, evaluate the operating conditions, such as ambient temperature and altitude, to ensure the pump’s reliability and performance.
Other factors to consider include maintenance, installation constraints, and the availability of spare parts and technical support. Choose positive displacement pumps that optimally match your application requirements to ensure efficient operation and the longevity of the equipment.
7 Essential Tips to Ensure Durability of Positive Displacement Pumps
Maintaining positive displacement pumps is critical for guaranteeing their peak performance and longevity in industrial applications. Here are seven maintenance tips that will keep these pumps functioning smoothly.
Regular Inspection
Conduct routine inspections of the pump and its components for signs of wear, leaks, or damage, including loose connections, cracked hoses, worn seals, and abnormal pump operation.
Lubrication Management
Ensure adequate lubrication of moving parts such as gears, bearings, and seals according to manufacturer recommendations. Monitor lubricant levels regularly and replenish lubricants as needed to prevent premature wear and friction.
Seal Maintenance
Ensure seals and gaskets are inspected for signs of deterioration or leakage. Replace worn seals promptly to prevent fluid leaks and environmental contamination.
Cleaning and Flushing
Regularly clean the pump internals and flush the system to remove debris and sediment that can impair performance or cause blockages. Always use compatible cleaning solutions and proper flushing procedures to prevent damage to the positive displacement pump and its components.
Temperature Monitoring
To prevent pump failure, monitor operating temperatures, ensure adequate cooling and ventilation, and address any issues causing excessive heat buildup.
Vibration Analysis
Regularly monitor pump vibrations using appropriate equipment to detect misalignment, imbalance, or other mechanical issues. Promptly address any abnormal vibration patterns to prevent further damage to the pump and associated equipment.
Training and Documentation
Ensure regular, comprehensive training for maintenance personnel on proper pump operation, maintenance procedures, and safety protocols. Keep detailed records of maintenance activities, including inspections, repairs, and replacements, to track pump performance and identify recurring issues.
Proactive maintenance practices for positive displacement pumps can reduce downtime, repair costs, and equipment lifespan, while also promoting safer working environments and enhanced operational efficiency.
