Industrial-pump manufacturer publishing the NEP portfolio. This dossier reviews one NPKS family brochure, preserving its two-stage single-suction configuration and separating it from other split-case families. Exact model, producing plant and current conformity remain procurement checks.
Select a family to see the source, dimensional range and questions to confirm. Images below identify product families. Read each caption for the source and illustration status.
Images are credited individually. Technical illustrations explain published dimensions; they are not factory photographs. Series photographs do not establish individual specifications.

Original comparison source ↗Brochure provides family envelopes, inlet sizes and speed options. A selected curve and current drawing are required; not every option is universally combinable.
Company publication ↗Official directory separates NPS from NPKS and lists other configurations. NPKS data must not be copied into NPS, fire-system or cryogenic models.
Company publication ↗The following identity information is attributed to the company website. It does not replace registration or supplier approval checks.

| Company-published history | Founded2004 in English overview; historical statement, not registry verification |
The English overview describes CNC turning, milling, boring, grinding and assembly equipment. This is a company description rather than verification of each order’s route or available capacity.
The overview describes a hydraulic test centre. Facility-envelope figures are not transferred into NPKS product limits or treated as test results for a shipment.
Obtain producing-site identity, controlled drawings, component/material traceability and an agreed test programme. No independent factory audit or current accreditation is asserted.
These are public-document leads. Current certificate validity and product applicability have not been independently established.
Six-page company-hosted brochure includes range, construction, material-option and direction diagrams. Its current revision/publication date is not established.
Request the current selected-model curve, dimensions, material schedule, driver/seal and full order designation.
Brochure distinguishes standard and special rotation viewed from the drive end.
Approve rotation, nozzle arrangement and interface drawing for the actual installation; do not infer from a family illustration.
The corporate site lists broad certificate claims, not current approval for the selected NPKS order.
Check certificate holder/site/scope/expiry and applicable standard edition; agree inspection and performance records.
Buyer guidance from Honyawn Atlas — not a statement of the manufacturer’s commercial terms.
State fluid composition, temperature, required flow/head, duty cycle and inlet conditions. Clean-water similarity must be confirmed for another liquid.
Agree stages/suction, full model, speed, rotation, materials and seal. Keep NPS and NPKS distinct.
Request current dimensions, connections, motor data, performance acceptance, traceability and inspection documents.
Confirm manufacturing and contracting entities, samples if needed, spares, commissioning, quantity and delivery terms. No price, stock or MOQ verified.
Include the drawing or standard, quantity per size and delivery destination. Select quotation, samples or technical documents in the request form.
