The Wilo BAC series is specially designed for the safe integration of chillers and heat pumps, and can be adapted to new - generation equipment including the R290 refrigerant. It can pump a variety of non - abrasive fluids and has the advantages of safety, energy - saving, convenient installation, reliability and durability. Wilo also provides related service support.
- Safety Guarantee: It is compatible with refrigerants up to R290 gas, ensuring a high level of safety for heat pumps and chillers. It has been tested by external laboratories and meets relevant standards.
- Energy - efficient and High - performance: The ultra - modern hydraulic components and motors achieve energy - saving. The pump has high hydraulic efficiency (MEI ≥ 0.7) and uses IE3 motors.
- Convenient Installation: It adopts Victaulic connections for quick installation. The pump size is optimized for easy replacement. Some models can optionally use quick - connect plugs for electrical connection, improving user comfort.
- Reliable Performance: High - quality mechanical seals and bearings ensure high reliability. The modern motor design reduces noise. Corrosion - resistant materials or coatings and maintenance - free roller bearings extend the service life.
- The high - efficiency pump hydraulic components and IE3 motors achieve significant energy - saving.
- The cast - iron components have a compact structure to reduce weight.
- The production in European factories is sustainable and carbon - neutral.
It is a monobloc glanded pump with Victaulic connections. It is a single - stage low - pressure centrifugal pump with an axial suction port and a radial pressure port.
It is used for pumping cooling water, cold water, water - glycol mixtures and other non - abrasive fluids. BAC50 can be used for R290 heat pumps (in accordance with IEC 60335 - 2 - 40).
For example, BAC 50/122 - 1.5/2. "BAC" represents a monobloc pump for cooling and air - conditioning applications. "50" is the pipeline connection (pressure port). "122" is the impeller diameter. "1.5" is the rated motor power P2 (kW). "2" is the number of poles.
- Temperature range: - 15°C to +90°C for BAC50, - 15°C to +60°C for BAC70.
- Power connection: 3~400V, 50Hz (other options can be provided upon request).
- Protection level: IP55.
- Victaulic connections: DN 50 (60.3mm) or DN 65 (76.1mm).
- Maximum working pressure: 10 bar for BAC50, 6.5 bar for BAC70.
- Pump housing: PA 6.6 50% GF for BAC70, EN - GJL - 250 for BAC50.
- Impeller: PA/PPO fiberglass - reinforced.
- Shaft: X30Cr13.
- Mechanical seal: BQEGG.
