PEDROLLO PQ60-Bs Peripheral Pumps With Brass Pump Body
PERFORMANCE RANGE
- Flow rate up to 50 l/min (3.0 m3/h)
- Head up to 95 m
INSTALLATION AND USE
Designed for pumping diesel/naphtha and clean water free from abrasive particles and non-corrosive liquids that do not harm the pump’s components. Their hydraulic characteristics, compactness, and small size make them ideal for industrial applications such as chillers, air conditioners, coolers, and boiler feed systems.
PUMP BODY
The pump body is made of CW617N brass, which guaran-tees protection against
rust and oxidation.
APPLICATION LIMITS
- Manometric suction head up to 8 m
- Liquid temperature between -10 °C and +90 °C
- Ambient temperature between -10 °C and +40 °C
- Maximum working pressure 10 bar
AVAILABLE UPON REQUEST
- Mechanical seal options available
- Protection rating IP 55 (only for PQ81-Bs and PQ65-Bs)
- Different voltage requirements 60 Hz frequency
PATENTS – TRADE MARKS – MODELS
- Motor bracket: Patent No. IT1243605
- Community Model No. 009068877-0001
