BSB Dual Line Grease Pump

Industrial-Grade Centralized Lubrication System The BSB Dual Line Grease Pump is a high-performance lubrication solution designed for demanding industrial environments. This electrically driven pump delivers consistent lubrication to multiple points simultaneously through its dual-line distribution system. With adjustable pressure up to 40MPa (400 bar) and multiple reservoir options, this robust system handles various lubricants including greases up to NLGI 2# and oils above 68#. The mechanical control of pilot pistons prevents common blockage issues, ensuring reliable operation even in harsh conditions from -20°C to 80°C. Technical Specifications Parameter Specification Maximum Pressure 40MPa (400 bar) Discharge Volume 120cm³/min (80rpm)<br>235cm³/min (160rpm)<br>365cm³/min (250rpm) Reservoir Options 30L, 60L, or 100L Operating Temperature -20°C to 80°C Compatible Lubricants Grease NLGI 000# to 2#<br>Oil above 68# How It Works The BSB pump uses a double-acting system with feed pistons and pilot pistons working together in a common bore. While one pair pulls in lubricant, the other pushes it out to your machinery. This design ensures continuous flow and prevents air from getting trapped in the system. Unlike pumps with hydraulic or spring controls, the BSB uses mechanical control for its pilot pistons, preventing blocking and ensuring reliable operation even in challenging industrial environments.

The BSB Dual Line Grease Pump delivers up to 40MPa (400 bar) of pressure, making it suitable for demanding industrial applications. This high-pressure capability ensures lubricant reaches all points in your system, even in extensive installations with long main lines. What kind of grease can I use with this pump? You can use grease from NLGI 000# to NLGI 2# grades, as well as oils above 68# viscosity. The pump’s robust design handles a wide range of lubricants, but we recommend consulting our technical team for specific compatibility information, especially for synthetic lubricants or special applications. How much lubricant can this pump deliver? The flow rate depends on the model and motor speed: P120Z delivers 120cm³/min at 80rpm P235Z delivers 235cm³/min at 160rpm P365Z delivers 365cm³/min at 250rpm This range of options allows you to select the appropriate flow rate based on the number of lubrication points and frequency requirements of your machinery. What reservoir sizes are available? You can choose between 30L, 60L, or 100L reservoirs depending on your operational requirements. Larger reservoirs reduce refill frequency, while smaller reservoirs may be suitable for spaces with limited installation area. Consider your maintenance schedule and lubricant consumption when selecting reservoir size. Does this pump work in cold environments? Yes, models with 0.75kW or 1.5kW motors operate in temperatures from -20°C to 80°C, making them suitable for outdoor installations and cold environment applications. Models with 0.37kW motors operate from 0°C to 80°C. For extremely cold environments below -20°C, optional heating elements can be provided. How heavy is the unit? The weight varies by model and configuration, ranging from 56kg to 82kg depending on the reservoir size, discharge capacity, and motor power. This information is important for planning installation logistics and ensuring proper mounting support. What are the shipping dimensions? The unit is packaged in a wooden box measuring 760mm×650mm×1300mm for safe transport to your facility. This protective packaging ensures the pump arrives in perfect condition, ready for installation. What power supply does the pump require? All models operate on 380V three-phase power supply. Ensure your facility has appropriate electrical connections before ordering. For locations with different power requirements, please contact us to discuss alternative configurations. How frequently does the system require maintenance? We recommend inspecting the pump every 3 months during normal operation. Key maintenance includes checking lubricant quality, inspecting seals, and ensuring proper pressure settings. A complete service is recommended annually, including replacement of wear components as needed. Properly maintained pumps typically provide 8-10 years of reliable service. Can I connect this pump to my existing lubrication system? Yes, the BSB Dual Line Grease Pump can often be retrofitted to existing dual-line distribution systems. Our technical team can evaluate your current setup and recommend appropriate connection components. We offer adapters for most standard connection types used in industrial lubrication systems. How does the dual-line system compare to single-line or progressive systems? Dual-line systems offer several advantages for large industrial applications, including: Better reliability for extensive installations with many lubrication points Continued partial operation even if one line is damaged Easier troubleshooting and maintenance compared to progressive systems More consistent pressure distribution across all lubrication points Better performance with higher viscosity lubricants Related: Grease Pump hub — types, selection guides, and troubleshooting.
