Positive Displacement Bilge Pump

● Series: QBY
● Type: diaphragm pumps
● Capacity: 0~30m3/h
● Head: 0~50m

Description

QBY diaphragm pumps are a type of positive displacement bilge pump. Unlike centrifugal pumps, these aren’t typical on large ships. Their capacity isn’t as high as centrifugal types, and they also aren’t very good at handling debris. However, for small and medium-sized boats, these offer several advantages. For one, they don’t need any priming. Diaphragm pumps can run completely dry, whereas centrifugal pumps will get damaged. Because of this, diaphragm pumps can remove all the water in the bilge.

Product Advantage

1. No electricity. It's safe and reliable while in the flammable and explosive places.

2. Pump has no rotor parts and bearing seals. The diaphragm will completely separate the exhausted medium and pump running parts, working medium. There's no leakage, thus it doesn't cause environmental pollution and human body safety dangerous while exhausting the toxin and flammable or corrosive medium.

3. It’s convenient to use and reliable to work. This pump is simple in structure and easy to be installed and maintained.

4. This pump doesn't need oil lubricant, even works in dry run.

Features:

● Air operate (no electric)

● Self-priming function

● Suitable for high viscosity water from boat bilge

● Head up to 50m

● Suction up to 7m
