Recommended Equipment
Centrifugal Pump
16 sub-series for water, wastewater, chemicals and multistage.
Screw Pump
Single and triple screw for viscous, high-temp and bitumen media.
Vacuum Pump
Liquid ring vacuum for industrial vacuum, wet gas and degassing.
Thermal Oil Pump
-20°C to 350°C, no cooling water. Chemical, textile, food, petroleum.
Key Selection Considerations
- Product viscosity and solids content — Thin products, process water and cleaning liquids suit the centrifugal series, which covers 0.75–10,000 m³/h at 2–1,800 m head and 0.18–1,120 kW. Viscous products, pastes and products carrying solids move selection toward positive-displacement screw pumping, covering 0.1–241.7 m³/h at 0.6–2.4 MPa.
- Process and cleaning temperature — Product temperature and cleaning temperature must both be confirmed. The screw pump series is rated up to 350°C on the 3GB triple-screw models, and materials and seals then follow from those conditions.
- Flow rate and discharge pressure — The transfer duty should be taken from the process rather than from the pump list, including the required discharge pressure at the duty point.
- Hygienic and cleaning requirements — The cleaning regime and the surface and material requirements of the specific process must be confirmed before equipment is proposed.
- Materials and seal compatibility — Wetted materials and seal arrangements should be checked against the product, its temperature and the cleaning chemicals in use.
- Hot oil circulation for thermal processing — Indirect heating duties such as dryers and fryers use the thermal oil series: 1–500 m³/h, -20°C to 350°C, 1–12.5 bar, with no cooling water required.
- Vacuum duty where applicable — For degassing, filling or evaporation duties, define the required vacuum level and gas load. The liquid-ring series reaches 33 mbar absolute at 0.45–8.33 m³/min.
- Duty cycle and installation layout — Operating hours, the tank or pipeline arrangement and the available space determine the final pump and motor configuration.
Engineering Approach
Duties are separated before equipment is chosen, because process-water circulation, thin-product transfer, viscous-product transfer and indirect heating have different operating requirements and are normally served by different pump types. The transfer duty is established first, covering product viscosity, solids content, temperature, flow and discharge pressure, and the hygienic requirements of the specific process are confirmed alongside it. To raise a technical recommendation, send the product or fluid, viscosity, solids content, required flow and head, operating temperature, cleaning regime, operating hours and site conditions.
Frequently Asked Questions
Which pump is suitable for a thin beverage product?
Low-viscosity products are normally handled by the centrifugal series, which covers 0.75–10,000 m³/h at 2–1,800 m head and 0.18–1,120 kW. The duty point should still be taken from the actual process.
Can one pump handle both thin and viscous products?
Not normally. Centrifugal and positive-displacement pumps address different viscosity ranges, so the two duties are usually reviewed separately.
What flow rate is available for viscous product transfer?
The screw pump series covers 0.1–600 m³/h at pressures of 0–6 MPa, and up to 350°C on the 3GB triple-screw models.
What temperature can the equipment operate at?
The 3GB triple-screw models are rated up to 350°C, and the thermal oil series covers -20°C to 350°C at 1–12.5 bar. Product and cleaning temperatures should both be reviewed.
Can thermal oil pumps be used in food processing?
Thermal oil pumps can be used for indirect heating systems such as food dryers and thermal processing equipment when the complete system and heat-transfer fluid meet applicable requirements.
Can hygienic requirements be met for a specific process?
Hygienic requirements depend on the specific process and should be confirmed before equipment is proposed. Material and cleaning requirements form part of that review.
How is a process water circulation pump sized?
From the required flow and head, which follow from the circulation rate, the pipe run and the pressure loss of the equipment in the loop.
Can the same installation be used for degassing?
Where vacuum is required, the vacuum level and gas load should be specified separately. The liquid-ring series reaches 33 mbar absolute with a maximum flow of 0.45–8.33 m³/min.
What information should be provided for a food or beverage plant duty?
The product or fluid, viscosity, solids content, temperature, required flow and head, cleaning regime, duty cycle and site conditions.
