**Trademark:** BAOSI or OEM
**Origin:** China
**HS Code:** 8414100090
**Application Areas:**
This vacuum pump is widely used in various industrial applications such as coating, lighting, vacuum drying, freeze drying, solar energy systems, analytical instruments, leak detection equipment, packaging, and heat treatment in metallurgy. Its versatility makes it suitable for both laboratory and industrial environments.
**Key Features:**
- Equipped with a springless rotary vane design, ensuring low noise and vibration levels.
- Incorporates an internal oil check valve to prevent oil backflow.
- Features an internal pump for continuous and stable operation under atmospheric pressure.
- Designed for long service life and reliable performance in demanding conditions.
**Technical Specifications:**
| Model / Project | BSV30 | BSV40 | Unit |
|-----------------------|---------------|---------------|----------|
| Pumping Rate (50Hz) | 30 (500) | 40 (667) | m³/min |
| Pumping Rate (60Hz) | 36 (600) | 48 (800) | m³/min |
| Ultimate Pressure (Gas Ballast On) | 2.0 | 2.0 | Pa |
| Ultimate Pressure (Gas Ballast Off) | 5.0×0.1 | 5.0×0.1 | Pa |
| Rated Motor Power (Three-phase) | 1.5 | 1.5 | kW |
| Motor Speed (50Hz) | 1400 | 1400 | rpm |
| Oil Capacity (Upper Limit) | 1.2 | 1.2 | L |
| Oil Capacity (Lower Limit) | 2.8 | 2.8 | L |
| Connection Diameter | VG40 | VG40 | mm |
| Outlet Diameter | KF40 | KF40 | DN |
| Weight | 63 | 65 | kg |
**Notes:**
1. The "ultimate pressure" values are measured using a Pilani vacuum gauge. If a McLeod vacuum gauge is used, the values may be significantly lower—up to one order of magnitude less.
2. All technical data is based on the instruction manual for the BSV series direct-connected oil rotary vane vacuum pumps.
