BM-B Grease Pump

Electric High-Pressure Lubrication Pump for Industrial Machinery Product Description The BM-B Grease Pump is a reliable electric lubrication pump designed for industrial machinery that needs consistent grease or oil delivery. Built by Bijur Delimon, this pump works in many types of lubrication systems and can handle high pressure up to 400 bar (5800 PSI). The pump comes with a built-in pressure relief valve that you can adjust from 0 to 450 bar (factory set to 400 bar). When using the hydraulic 4/2-way valve SA-K, remember the pressure should not go above 350 bar. You can choose from three reservoir sizes (8, 15, or 30 liters) to match your needs. The pump delivers 34 cm³/min at 63 rpm or 67 cm³/min at 125 rpm, depending on your setup. It works in temperatures from -20°C to 80°C and can handle different lubricants – from grease up to NLGI class 3 to mineral oils ranging from ISO VG 68 to 1500. Many customers report that using the BM-B Pump reduces their maintenance time by about 30% and extends machine life by keeping parts properly lubricated. The compact design makes it easy to install in most industrial settings.

A: Most customers check their pumps every 3-6 months. Simple maintenance includes checking filter cleanliness and ensuring proper lubricant levels. With normal use, the pump itself can run for years without major service. Q: Can I use this pump outdoors? A: Yes, the BM-B Pump works in temperatures from -20°C to 80°C. However, you should protect it from direct exposure to weather when possible. Q: How many lubrication points can one pump handle? A: Depending on your setup, a single BM-B Pump typically handles between 15-100 lubrication points. The exact number depends on how far the points are from the pump, what lubricant you’re using, and how much each point needs. Q: How do I know which reservoir size to choose? A: This depends on how many points you’re lubricating and how often the system runs. As a general rule, the 8L tank works for small to medium systems, 15L for medium systems, and 30L for large systems with many lubrication points. Q: What’s the typical lifespan of this pump? A: With proper maintenance, most BM-B Pumps last 7-10 years in normal industrial conditions. Many customers report pumps still working reliably after 12 years. Q: Can it be connected to machine controls? A: Yes, the pump can be integrated with your machine controls, especially when you add the optional level switch or pressure gauge. This lets you monitor lubrication system status along with other machine functions. Need installation help or have technical questions? Contact our support team.
