Frequently Asked Questions
The questions buyers ask before a separator is specified — answered against the parameters published for the JY-N95, including the cases where centrifugal separation is the wrong tool.
These answers describe the machine as documented, not as marketed. Where a value depends on your fluid, it is stated as dependent rather than given a figure. Where a limit exists, it is named.
Fit and applicability
Whether centrifugal separation applies to your fluid at all. These questions decide the answer before any model selection.
How do I know whether the JY-N95 suits my fluid?
Three characteristics decide most of it: the density difference between solid and liquid, the particle size band, and the solids loading. The guidance published on this site is a density difference of about 0.1 g/cm³ or more, solids in the single-digit micron range and above, and roughly 1–50 % suspended solids by weight. These describe the feed material the process can accept — they are not a separation rating of the machine. The answer for your plant comes from evaluating your own fluid data, and where the fine end matters, from a test on the actual fluid.

What density difference does centrifugal separation need?
The driving force is the difference in density between the solid and the liquid — not particle size alone. Around 0.1 g/cm³ or more is the recommended working range. Below roughly 0.05 g/cm³ the settling rate falls away sharply and throughput has to be traded off; solids that sit close to the fluid density may need a different technology altogether.

Can the JY-N95 remove dissolved substances or adjust fluid chemistry?
No. Centrifugal separation acts on suspended solids that are denser than the liquid. Dissolved salts, dissolved metals, surfactants and pH are not changed by the process — those need chemical treatment, ion exchange, membrane processes or another step in the fluid-management chain. If dissolved contamination is the main problem, a separator is not the right tool on its own.

What happens if my fluid is a stable emulsion?
A stable emulsion offers no meaningful density difference to work with, so the field has little to separate. Emulsions usually have to be broken — chemically, thermally or by another pre-treatment — before centrifugation becomes effective. Whether that is practical for your fluid is a question for the evaluation, not something assumed in advance.

Can it handle high-viscosity fluids?
Only once the flow behaviour has been evaluated. Viscosity slows particle migration and reduces the achievable flow rate, so a high-viscosity medium runs at the lower end of the 25–120 L/min range — or may not be suitable at all. Viscosity at operating temperature is one of the first data points we ask for.

Does the separator replace my existing filtration?
Usually not entirely. In most plants centrifugal separation is one step in the loop: it removes the fine solids that blind filter media, which can extend media life and reduce change-out frequency. Bag or cartridge filters, magnetic separation or settling may still have a role downstream. This site does not claim that filtration can be removed — that depends on your cleanliness target and on the process.
Sizing, flow and installation
The published parameters, and what they do and do not tell you about throughput.
How do I choose an operating flow rate within 25–120 L/min?
The range is the envelope, not a fixed throughput. Flow is set by viscosity, the density difference, the solids loading and the cleanliness you are aiming for: higher viscosity or a tighter target means lower flow and longer residence time. Start from your actual circulating rate, then confirm the achievable rate against your fluid data during the evaluation.

Is 2200 G a filtration rating?
No. 2200 G is the rated centrifugal acceleration — an acceleration parameter. It is not a micron rating and cannot be converted into one, because the result also depends on particle density and size, liquid viscosity, residence time and machine geometry. A G value and a filtration precision are different quantities and are not interchangeable.

Can the separator be integrated into a centralised coolant system?
The machine is designed for continuous operation with automatic solids discharge, which is what a centralised system needs. Whether it fits your loop depends on the available flow, the head and pressure at the connection point, the tank arrangement, and how the discharged solids are handled. Those points are reviewed as part of system design rather than assumed.

What power supply and connected load does it need?
380 V, 50 Hz, with a 4.0 kW motor. If your site runs a different voltage or frequency, that has to be addressed in the order configuration — the standard machine is built for 380 V / 50 Hz.
Related: Published specifications
What space and connections should I plan for?
Overall dimensions are 1370 × 780 × 1815 mm. On the standard configuration the inlet is DN20 and the outlet DN100 (4 in). Plan working space around the machine and a route for the collected solids, not just the footprint — the sludge handling arrangement has to be decided at layout stage.
Related: Specifications and connections
What pH range is acceptable?
pH 6–9 is the published range, and it is a per-fluid confirmation rather than a universal compatibility statement: the fluid's chemistry, concentration and temperature all bear on wetted-part compatibility. Unusual or aggressive chemistry is reviewed before any commitment is made.

Solids, discharge and what comes out
What happens to the solids, and what you have to plan for downstream.
How are separated solids discharged?
Automatically. The JY-N95 is an automatic-discharge machine, which is what allows it to run continuously without stopping for manual bowl cleaning. The discharge mechanism and cycle details are confirmed with the machine configuration and the documentation supplied at order stage.
Related: Working principle
How often does it discharge?
The cycle is set to the solids load rather than to a fixed interval. A fluid carrying a high suspended-solids load needs more frequent discharge than a lightly loaded one, and the setting is part of commissioning. Because it follows your fluid, no single interval is published here.
Related: Solids handling in practice
What solids loading can it accept?
Approximately 1–50 % suspended solids by weight is the published feed band. That wide range is why the discharge cycle is set to the load rather than fixed. At the upper end, the handling of collected solids — not the separator — usually becomes the constraint on the process.
Related: Feed-material criteria
What happens to the collected solids?
They leave the machine as a concentrated sludge that has to be handled, stored and disposed of — or recovered, where the solids have value. The separator concentrates the solids; it does not make them disappear. Planning the sludge route (container, skip, dewatering, recycler) is part of the installation, not an afterthought.

Can it handle abrasive solids?
Abrasive solids are common in grinding and lapping fluids, and they are a material-selection question as much as a separation question. Whether a given abrasive is acceptable depends on the solids, the duty cycle and the wetted-part specification — it is confirmed in the evaluation, not assumed from the application name.

Maintenance, spares and documentation
What the machine consumes, what has to be inspected, and what arrives with it.
Does the machine use filter media or consumable cartridges?
No. The JY-N95 separates by centrifugal force and requires no filter media — there are no media elements or cartridges to replace. Electricity, scheduled maintenance, spare parts and solid-waste handling still apply.
What maintenance does it need?
Scheduled maintenance per the operation and maintenance manual: inspection of rotating components, seals and the discharge system, plus the checks defined for your configuration and duty cycle. Intervals depend on how the machine is run and on the fluid, so they are set with the documentation rather than published as one figure for every site.
Related: Maintenance planning questions
Which spare parts should be stocked?
The parts list is supplied with the machine documentation and confirmed per order, because it follows the configuration. For a remote site the practical approach is to hold the wear items identified in that list rather than a generic kit.
Related: Ask about a parts list
What documentation is supplied with the machine?
Operation and maintenance documentation, electrical information, and the order documentation covering the configuration supplied. The exact document set is confirmed with the order — if your site needs a specific format or language for maintenance records, raise it during the order rather than after delivery.

Quotation, delivery and support
What happens between an inquiry and a running machine, and what support looks like afterwards.
How do I get a quotation?
Send your application data through the inquiry form, or by email or WhatsApp. A quotation follows an engineering review of the fluid and duty: model confirmation, configuration, scope of supply and commercial terms. We reply within 24 hours and aim to return a proposal within three working days of receiving usable data.
Related: Send application data
What information makes the evaluation faster?
Fluid type and chemistry, contaminant description and approximate concentration, particle size information if you have it, viscosity and operating temperature, required flow rate, target cleanliness, current treatment method and installation constraints. Estimates are acceptable — waiting for perfect data delays the answer without improving it.

Can suitability be confirmed before purchase?
The published parameters describe the feed material the process can accept; the fine end of separation capability must be confirmed by test on the actual fluid under stated operating conditions. How that confirmation is arranged depends on the application, the fluid and your location — it is agreed during the evaluation rather than promised in advance.

What are the lead time and delivery terms?
Lead time and Incoterms are stated in the quotation, because they depend on the configuration, the options selected and the destination. No standard figure is published here that would not hold for your order.

What support is available after delivery?
Technical support is provided remotely — by email, WhatsApp and video, with the machine documentation as the reference. We do not claim an on-site service network covering every country: where an issue cannot be resolved remotely, the next step is agreed case by case rather than promised as a standard response.
