Positive displacement pumps
Application:
The internal gear pumps type R are positive displacement rotary pumps. The capacity is directly proportional to the rotation speed. This robust pump is very
successfully used for pumping high viscous liquids like for example bitumen.
Characteristics:
- Self-priming
- Heating optional
- Safety valve optional
- ATEX optional
- Simple and robust construction
- In-line version available
Materials:
- This pump can be made of stainless steel 1.4408 (AISI 316), cast iron EN-GJL-250 and nodular cast iron EN-GJS-400
- Shaft sealing alternative with mechanical seal, stuffing box or magnetic drive. The materials and the execution of the mechanical seal, packing or magnetic drive in accordance to the liquid.
Technical data:
- Q max.: 350 m³/h
- Viscosity: up to 100.000 mm²/s (cSt)
- Max. nominal pressure: PN16 (16 bar)
- Temperature liquid: -60 to 300°C
- Connections: DN40 - DN250
Application:
Lobe pumps of series “B” are positive displacement rotary pumps. The capacity is directly proportional to the rotation speed. Two synchronously driven rotors are rotating in a casing. This design provides a very gentle pumping of fluids.
Characteristics:
- Heating optional
- Safety valve optional
- ATEX optional
- Series B with flexible coupling, Series BE monobloc design
- Pumping in both directions
- Self-priming
- Easy and simple cleaning (SIP, CIP)
- Countless versions and options available
Materials:
- All hydraulic parts are made of stainless steel AISI 316. Special alloys and surface hardenings available on request.
- Shaft sealing alternative with mechanical seal, stuffing box or special lip seal. The materials and the execution of the mechanical seal, packing or lip seal in accordance to the liquid.
Technical data:
- Q max.: 300 m³/h
- Viscosity: up to 110.000 mm²/s (cSt)
- Nominal pressure: PN10 (10 bar), PN20 (20 bar) optional
- Temperature liquid: -40 to 200°C
- Connections: DN25 - DN200
Application:
The air operated double diaphragm pumps of type “DDA” are used for pumping a variety of different liquids (mainly chemicals), without abrasive, coarse or extended solids. These pumps can be installed submerged in the pumped liquid. The DDA pumps are self-priming. And they can be used for thin and viscose fluids. This series contains special pumps for food industry named “DFA”.
Characteristics:
- ATEX optional
- Self-priming
- Capable of dry running
- No shaft seal needed
Materials:
- The air operated double diaphragm pumps are made of PP (glass fiber reinforced polypropylene), PVDF, carbon fiber filled PVDF, Aluminium or stainless steel AISI 316 (AISI 316 polished - FDA).
Technical data:
- Q max.: 40 m³/h
- H max.: 70 m
Application:
The air operated double diaphragm pumps of type “DDE” are used for pumping a variety of different liquids (mainly chemicals), without abrasive, coarse or extended solids. These pumps can be installed submerged in the pumped liquid. The DDE pumps are self-priming. And they can be used for thin and viscose fluids. This series offers also a special FDA version for the food industry.
Characteristics:
- Self-priming
- Capable of dry running
- ATEX optional
- No shaft seal needed
- Solids up to 8,5mm size (depending on pump size)
Materialien:
