Quantum - Model DDQ 1 Inch - 0-320 -Diaphragm Pump
Solid-block construction made of pure thermoplastic polymers (PTFE) Available in size 1/2" - 1" - 1 1/2" Capacities up to 450 l/min Variable flow and pressure High chemical resistance and mechanical strength Non-icing air valve system Low air consumption Free-fastening diaphragm (from the shaft) Structural compactness Super easy maintenance Maximum safety For aggressive liquids, highly-viscous and/or heavy liquids, shear-sensitive liquids, inflammable liquids ATEX Zone 2 (Serie II 3/3 IIB T4) Conformity Ex.
Our new AODD pumps are realised from a solid-block construction of pure thermoplastic polymer material - PTFE. The main characteristics are similar to our ASTRA range - safety, run-dry, shear sensitive, dead-head, variable flow, variable discharge pressure, resistance to a wide variety of fluids, easy installation, easy maintenance and compliance with ATEX standards - but QUANTUM offer functional innovation, structural and constructive compactness.
They also ensure a more solid and precise execution when compared to what you can get from competitors` solid-block pumps. They are currently available in size 1/2", 1", 1 1/2" and 2".
- Capacity: up to 650 l/min
- Heading: up to 70 m
- Wetted parts: PTFE
Quantum AODD pumps are suitable to operate in explosive atmospheres classified Zone 2 (Series II 3/3 GD IIB T4). For applications classified Zone 1 (Series II 2/2 GD IIB T4), we manufacture pumps made of conductive parts for all versions.
- Double diaphragm
The construction of QUANTUM pumps also included free-fastening diaphragms. This allows an easy maintenance, more safety when pumping aggressive liquids and reduced air consumption.
- Valves
It is possible to disassemble the valves for maintenance without disassembling the entire pump already installed on the plant.
- Gasket
AODD pumps are usually suffering from ice formation in the distribution system. Our engineers propose an additional gasket located nearby the distribution system for moving the exhausted air, at low temperature, towards the discharge chamber. Thanks to this gasket, QUANTUM pumps are not sensible to humidity in the air so there is no influence on the efficiency.
- Capacity: up to 150 l/min
- Heading: up to 70 m
- Wetted parts: PTFE
PTFE
QUANTUM pumps are available in solid-block PTFE, which is a superior thermoplastic polymer offering to pumps high mechanical strength and high chemical resistance. PTFE material makes QUANTUM pumps ideal for handling the hardest liquids (nitric acid, hydrochloric acid, sulfuric acid, sodium hydroxide, potassium hydroxide,...)
