ISO Range · DN Non-Clogging
The DN range moves what plugs other pumps: sludges and slurries carrying large particles or long fibres. The hydraulic design keeps the passage open and lets big particles pass; gas removal systems extend the range to duties containing air or gas.
Pressures 16 bar (230 psi), by material and size. Series-level figures bound the envelope; the operating point of the specific size governs, confirmed on the reviewed curve.
Quick Selection Summary
| Capacities | to 2,000 m³/h (8,800 US gpm) | Heads | to 90 m (295 ft) |
| Pressures | 16 bar (230 psi), by material and size | Temperatures | to 180 °C (355 °F) |
Series-level figures bound the envelope; the operating point of the specific size governs the selection. Performance is confirmed against your duty point during the review.
Features and Benefits
- Designed for pumping abrasive or corrosive liquids, sludges and slurries containing large particles or long fibres
- Special hydraulic design prevents plugging and lets big particles pass
- Gas removal systems broaden the scope to applications containing air or gas
Applications
- Large solids containing liquids
- Large solids containing fibrous slurries
- Large solids and gas containing liquids and slurries
- Large solids containing liquids and slurries in self-priming applications
Design & Manufacturing
The DN range applies the European single stage conventions to solids-laden service: an open passage shaped against plugging, with gas removal systems for air- or gas-containing duties.
Wet-end castings run through YSM’s own foundry routes — sand, lost-foam and V-process — with traceable inspection reports; the material grade is confirmed to the liquid at selection.
Dimension tables are not published for this range. Envelope and interface dimensions are confirmed against your installed pump or project datasheet during the selection review.
Replacing Installed Pumps
The DN range is offered as a non-OEM alternative for equivalent Sulzer-type installations; replacement feasibility and interface dimensions are confirmed against the installed pump’s documentation during the selection review.
Start from the ISO 5199 / ISO 2858 range hub, or send the nameplate with the duty as run today.
Request a Selection
A complete enquiry closes in one review cycle. Include the duty point — normal, minimum and maximum flow with required head — the liquid with its concentration, temperature, specific gravity, viscosity and solids; the wetted material and sealing arrangement in service; documentation of the installed pump where this is a replacement; motor voltage and frequency; and quantity, inspection or documentation needs, destination and target delivery date. Anything unknown can be stated as unknown — a marked gap is reviewable, a silent one is not.
Prepare it faster with the selection data guide; then send the enquiry.
DN Non-Clogging Pump FAQ
What solid size can the DN pass?
The passage is designed to let big particles and long fibres through, but the admissible size is confirmed size-by-size at selection rather than promised from a table.
Can the DN replace an installed Sulzer-type pump?
Yes — the range is offered as a non-OEM alternative for equivalent Sulzer-type installations. Replacement feasibility and interface dimensions are confirmed against the installed pump’s documentation during the selection review; nothing is promised from a family name.
Do you publish dimension tables for this range?
No. Selections are quoted against the duty point and the installed pump’s documentation; envelope and interface dimensions are confirmed during the selection review rather than read from a published table.
Which materials are available?
Wet-end castings are produced through YSM’s own foundry routes — sand, lost-foam and V-process — with traceable inspection reports. The material grade is confirmed to the liquid and its concentration at selection.
What data closes a selection in one cycle?
The duty point as run today, the liquid with temperature and concentration, the wetted material and sealing arrangement in service, documentation of the installed pump where this is a replacement, motor voltage and frequency, and quantity with destination. Anything unknown, stated as unknown.
What are the lead time and warranty for this pump?
Typical lead time is 4 weeks for a complete pump, 2 weeks for a bare wet end and 1 week for replacement parts, from deposit and approved drawings. Warranty is 12 months from shipment against defects in materials and workmanship within the reviewed duty. Late shipment attributable to YSM is compensated at 0.5% of contract value per week, capped at 5%.
What are the payment and delivery terms?
30% T/T deposit within 7 days of order, 70% T/T before shipment, or irrevocable L/C at sight; export-grade wooden-case packing; any Incoterms 2020 term (EXW Zibo, FOB Qingdao, CIF, DAP/DDP) as agreed in the quotation. Factory witness testing and third-party inspection (SGS, BV, TÜV) are accepted. Full terms: Commercial Terms
