As a trusted supplier from Rossonix Co., Limited (established in 2011, ISO 9001 certified), we are proud to introduce the SEIM Screw Pump PB020 – a robust positive displacement screw pump specifically engineered for heavy oil transport. With over a decade of export experience and annual export value exceeding US$5 million, our company ensures that every pump delivers reliable performance in demanding industrial environments. Whether you are moving crude oil, bunker fuel, or high-viscosity lubricants, the PB020 offers exceptional efficiency, smooth flow, and long service life.
The SEIM PB020 is a three-screw pump design that provides virtually pulsation-free flow, making it ideal for applications where stable pressure and low noise are critical. Its compact construction and high self-priming capability allow for easy integration into existing pipelines. Below we detail the key features, technical specifications, and benefits that make this pump a top choice for heavy oil transportation.
Key Features & Advantages
High Viscosity Handling: Capable of pumping fluids with viscosities up to 100,000 cSt, ensuring reliable transfer of heavy oil without cavitation.
Self-Priming & Dry-Run Protection: Excellent suction lift and optional dry-run protection devices safeguard the pump during start-up or low fluid conditions.
Low Noise & Vibration: The balanced screw design minimizes pulsation, noise levels below 70 dB(A) under normal operation, enhancing workplace comfort.
Durable Construction: Available in cast iron, ductile iron, or stainless steel to withstand corrosive environments and abrasive particles.
Easy Maintenance: Cartridge-type mechanical seal and replaceable liners reduce downtime and simplify servicing.
Energy Efficient: Optimized internal clearances reduce internal leakage, resulting in volumetric efficiency up to 95%.

Frequently Asked Questions
Q: What type of heavy oil can the PB020 pump handle?
A: It is suitable for crude oil, bunker fuel, heavy fuel oil, used lubricating oil, and other high-viscosity fluids up to 100,000 cSt. For specific fluid compatibility, please share your fluid properties with our sales team.Q: Is the pump self-priming?
A: Yes, the PB020 has excellent self-priming capability and can lift oil from depths up to 6 meters under normal conditions. A foot valve is recommended for long suction lines.Q: What materials are available for the pump wetted parts?
A: Standard material is cast iron, with optional ductile iron, carbon steel, or stainless steel (SS304/SS316). Seals can be selected based on fluid temperature and corrosiveness.Q: Can the pump run dry for short periods?
A: The pump is not designed for continuous dry running. However, we offer optional dry-run protection devices (e.g., flow switch or temperature sensor) to prevent damage.Q: What is the typical maintenance interval?
A: Under normal operating conditions, we recommend replacing the mechanical seal and bearings every 8,000 to 10,000 operating hours. Regular oil change and inspection of wear parts extend service life.Q: Do you provide customized motor packages?
A: Yes, we can supply the pump with an electric motor (standard or explosion-proof), coupling, and baseplate. Motor power and voltage can be customized to your local electrical standards.Q: What certifications does the PB020 have?
A: Our manufacturing facility is ISO 9001 certified. The pump itself can be supplied with test certificates (material, hydrostatic, performance) upon request. Additional certifications (e.g., ATEX) are available as optional extras.Q: How long is the warranty period?
A: We offer a standard 12-month warranty from the date of shipment against manufacturing defects. Extended warranty options are negotiable.
