Centrifugal pumps
General transfer, boosting and process duty. Flow, head, viscosity, temperature and seal arrangement determine the hydraulic and mechanical selection.
Product group 02 · Power & flow
Pumps, motors and drives, matched to the duty and installation.
A pump or drive is only correct when flow, head, power, mounting and environment are considered together. Send the duty point, nameplate details or drawing and we will help build a clear supply request.

Product families
Common types and what distinguishes them.
Submersible & water pumps
Drainage, water supply and sump duty. Installation depth, solids handling, voltage and duty cycle need to be stated.
Process & dosing pumps
Chemical, metering and process applications. Wetted materials, accuracy, pressure and control method are part of the specification.
Electric & gear motors
Standard and geared motor options. Power, voltage, frequency, frame, mounting, protection and duty class must be confirmed.
Gearboxes & speed reducers
Ratio, torque, input speed, mounting and service factor determine the unit. Output shaft and flange details must match the driven equipment.
Couplings & shafts
Power transmission between driver and driven equipment. Bore, keyway, length, material and balancing requirements need to be specified.
Bearings, belts & chains
Replacement and production components. Dimensions, load, speed, environment and preferred brand or equivalent need to be stated.
Specifications vary by model and supplier; all technical data is subject to confirmation upon inquiry.
Custom requirements
Standard product not enough?
Available supply options may include standard products and customized specifications, subject to project requirements. Share a drawing, sample or performance requirement and we will review suitable manufacturing and supply options.
Discuss Custom RequirementsMaterials & standards
The details that change the quote.
The ranges below are common industry references, not a statement of stock or supplier capability. The applicable grade, standard and test requirement must be confirmed for the specific inquiry.
- Wetted materials
- Cast iron, stainless steel, bronze, duplex and selected alloys depending on the medium. Pump casing, impeller and seal materials should be confirmed together.
- Motor specification
- Power, voltage, phase, frequency, poles, frame, mounting, enclosure and insulation class. Confirm the local supply and driven load before selection.
- Performance data
- Flow, head, efficiency, speed, pressure and temperature. A pump curve or duty point is more useful than a product name alone.
- Mechanical interface
- Flange standard, shaft diameter, keyway, coupling, baseplate and rotation. These details determine whether the unit will fit the installation.
- Environment
- Indoor/outdoor, ambient temperature, dust, moisture, corrosive atmosphere and duty cycle. Confirm any protection requirements with the supplier.
- Documentation
- Nameplate data, test reports, drawings and material certificates can be requested where available and confirmed by the selected supplier.

Before you buy
Purchasing considerations.
Define the duty point
Flow and head are the starting point. Temperature, viscosity, solids and suction conditions can change the required pump and motor.
Check the mechanical fit
Flange sizes, shaft, coupling, baseplate and rotation must match the existing installation. A hydraulically suitable pump can still fail at installation.
Confirm the electrical supply
Voltage, phase, frequency, control method and starting arrangement must be known before a motor or drive is quoted.
Plan for spares
Seals, bearings, wear parts and couplings may need to be included in the first order. Ask what is consumable and what is project-specific.

FAQs
Common questions about pumps, motors & drives.
Can you quote a replacement pump from a nameplate?
A clear nameplate photo and installation details are a good start. Flow, head, pipe connections and motor data may still be needed to identify a suitable replacement.
Can you supply motors for different voltages and frequencies?
Motor options depend on the supplier and the required market. State voltage, phase, frequency, mounting and duty; we will confirm what is available before quotation.
Do you supply gearboxes separately from motors?
Yes, where the ratio, torque, mounting and interface are defined. A complete gear-motor package may be more practical for some applications.
Can you source spare parts and bearings?
Replacement bearings, seals, couplings and shafts can be quoted from dimensions, nameplate data or samples. Verification of the existing part is the buyer’s responsibility unless a sample check is agreed.
Can performance be customized?
Customized performance, voltage, materials and mounting can be explored subject to the selected supplier’s capability. Test and acceptance requirements should be agreed before production.
