Source Aquatec pumps for reverse osmosis, water delivery and recirculation. Send the operating point, power supply and system details; for replacement, include the installed pump marking.
Start with the function: RO pressure boosting, delivery, recirculation, permeate pumping or off-grid water supply. Then identify the model and installation requirements.
These families raise the inlet pressure supplied to a reverse osmosis membrane. For a replacement, identify the complete pump code and the electrical supply. Include the tube connections and explain how the system stops the pump when its tank is full.
A series number is a starting point for selection; the suffix on the installed unit identifies the configuration that needs to be checked.
The 3300 uses front ports, while the 5300 has an inline port arrangement. This matters when the pump has to fit inside an existing enclosure. Send a photograph showing the available space and the direction of the tubing.
For a new installation, describe the membrane system and the operating point; for maintenance, start with the installed model and the original equipment specification.
Demand/delivery pumps move water from a source to its point of use. The manufacturer lists 550 and 5800 variants for this purpose. Explain whether water comes from an atmospheric tank or a pressurised line, and describe how demand is detected. Include the voltage and the complete model marking.
If several machines share one supply, describe that arrangement separately from the requirements of an individual machine.
Transfer and recirculation applications include moving liquid between vessels and circulating coolant through a circuit. Record the liquid composition, temperature and required flow at the actual resistance of the system. Include pipe size, heat exchanger details and the intended operating cycle.
When replacing an installed pump, distinguish the original specification from any changes made to the circuit since it was commissioned.
Aquajet variable speed pumps use integrated electronic control to respond to changing demand. Describe the outlets, the number expected to operate together and the pressure required at those outlets. Keep the original controller and wiring information with a replacement enquiry.
An installation designed around a variable speed pump should be described as a complete control arrangement, including any existing storage vessel and external controls.
ERP500 and ERP1000 are permeate pumps driven by hydraulic energy from the reject stream. They perform a different function from an electric booster upstream of the membrane. For selection, send the RO diagram and identify the membrane, storage tank and shut-off arrangement.
Mark the connections visible on the installed unit. This makes it possible to discuss the correct position in the circuit before comparing individual models.
SWP-4000 and SWP-6000 are submersible diaphragm pumps for off-grid water supply. An enquiry should describe the water level, lift to the delivery point, pipe route and available power source. State whether the installation uses batteries or solar modules with a controller.
Include the installed controller designation for maintenance work, and separate the required pump from cables, controls and other installation items.
Accessories should be identified by their function and connection to the pump circuit. Aquatec lists inlet strainers and ACT820 accumulator options; booster applications also use pressure switches and flow-control components. Send the marking of each installed item and a connection photograph.
For an assembly enquiry, list every component on a separate line so that a pump, an electrical control and a vessel are not treated as one unspecified kit.
Aquatec International is a US manufacturer of electric diaphragm pumps. Start by identifying the actual product: an RO booster, a delivery pump, a permeate device or a submersible pump. Photograph its complete label and keep every suffix in the model code.
If it is installed inside another manufacturer’s machine, provide both the pump label and the machine identification. Describe the function in the system as well as the brand. This gives the enquiry a clear technical starting point before the equipment specification is compared.
State the assembly level you need: an individual service item, a subassembly or the complete pump. For a diaphragm, valve assembly, seal or motor, include the item reference from documentation for that particular pump.
If no parts list is available, send an overall view, the nameplate and the location of the required component. Keep a repair item and a complete replacement pump as separate quotation lines.
List the fittings, power supply and mounting items required with either option so the alternatives can be compared on an equivalent basis.
Give the required flow at the required pressure, with a note of where the measurements apply. The pump outlet, membrane inlet and final point of use may have different conditions. Add inlet pressure, tube size, route length and changes in elevation.
If the system has been expanded, list the added consumers, filters or heat exchangers. For several operating modes, provide a short table of flow, pressure and duration. These details frame the selection around the actual circuit rather than two unrelated maximum catalogue values.
Copy the electrical rating in full, including AC or DC. Photograph the supply, wiring and connector before removing the old unit. Explain whether the pump is switched by its own pressure switch, an external controller or the host machine.
If you only need a control component, provide its marking and wiring diagram. Keep the previous agreed specification for a repeat purchase. Similar housings and connectors are useful identification clues, but the electrical data must remain part of the enquiry for every individual pump.
Identify the liquid, its concentration and the operating temperature. For a mixture, attach the technical description or safety data sheet instead of using a broad term such as chemicals. Include cleaning fluids that may pass through the pump even when its main duty is water delivery.
Describe exposure and storage conditions for an outdoor installation. Record running and rest periods for an intermittently operated machine. These requirements belong in the initial enquiry because flow alone does not describe the conditions experienced by the pump materials and connections.
Describe the observed behaviour: failure to start, insufficient delivery, repeated switching, unusual noise or a visible leak. Separate checks already performed from a suspected cause.
Useful information includes the measured supply, inlet strainer condition and photographs of the tubing or leak location. If the problem began after maintenance, list the changed parts and connections. Mark the required service item on a photograph or drawing.
Begin with accessible labels and existing documentation; the enquiry should explain the purchasing need without requiring unnecessary disassembly.
For multiple items, prepare a list with the full code, function, quantity and a reference to a photograph or drawing. Give the pump, strainer, switch and power supply their own lines. Leave unknown fields blank and attach evidence instead of completing a model code by guesswork.
Show quantities by machine if several installations are involved. Use file names that can be matched to the corresponding list entry. Include the receiving location and the documentation required by your purchasing process so the proposed scope can be checked before ordering.
Use the previous specification for a repeat purchase and list changes in quantity, equipment, power, liquid or installation separately. For an alternative, explain which requirements may change and which must remain fixed.
On receipt, compare the marking, quantity and included items with the agreed list, and retain labels and documents for incoming inspection. The equipment documentation should define the checks before installation and operation.
Keep a photograph of the new nameplate and the final specification with the machine records to support later maintenance and repeat orders.
Specify flow at the operating pressure, inlet conditions, liquid, temperature, electrical supply and duty cycle. A circuit diagram helps account for the tank, membrane, filters and controls.
List the pump and each service item separately. For a component, include the part number or drawing reference; for a repeat order, attach the previously agreed specification.
Availability, price, lead time, scope, origin, certificates and warranty are agreed for the specific item. Official dealership and unchecked compatibility are not claimed; service parts and earlier variants require verification by the full code.
