About the VTN-1DU pump
VTN-1DU is the flagship of the series — not "the same pump, only stronger", but different hydraulics. An impeller from 340 mm at reduced 1000 rpm with a 22–50 kW drive delivers the highest capacity in the range; the highest head — up to 40 m — is the limit of a version with an enlarged impeller. Like the whole series, the VTN-1DU moves raw manure from 75% moisture without water dilution. The 1.5 to 3 m column and submersion from 0.5 to 10 m are meant for deep tanks; mixing at the intake covers a radius of up to 7 m — on a large lagoon, one unit covers the whole zone.
Key features:
- The highest capacity in the range: up to 650 t/h on liquid and up to 450 t/h on viscous manure (85% moisture) — one unit instead of two base pumps
- Pumping distance up to 2 km — to remote storage without intermediate pumping stations; head up to 40 m is the range's maximum
- Deep tanks: submersion from 0.5 to 10 m, a pump column from 1.5 to 3 m
- Mixing radius up to 7 m — the mass is homogenized without a separate mixer even in a large lagoon
- Cutting mechanism: solids up to 45 mm, fibres are not limited
Applications:
- Large livestock complexes: big manure collectors and lagoons, pumping to remote storage and fields — up to 2 km.
- Treatment plants and sewers: large volumes of effluents and sediment over long lines.
- Industrial sites: process effluents with sediment, deep receiving tanks.
VTN-1DU goes where volumes and lines have outgrown the base model: a large farm, a deep tank, remote storage. For typical manure collectors the VTN-1 is enough; when mixing matters more than volume, look at the compact VTN-1M; and when there is no grid at the site, the PTO-driven VTN-1MT does the job.
One unit instead of two
When the volumes have outgrown the base pump, the usual answer is a second pump or an intermediate booster station on the way to a distant store. The VTN-1DU covers the same task with a single unit: up to 650 t/h on liquid manure and a distance of up to 2 km (depends on flow rate and pipeline diameter). The head reaches up to 40 m on a separate version; the working limits are matched to the task. Fewer pieces of equipment means less installation, less wiring and fewer points of failure.
The larger the herd, the more the dilution water costs: by our model a 1,000-cow complex loses roughly BYN 59,000–132,000 a year on it, and a 2,000-cow one twice that (a model estimate on conservative assumptions). Your own figures go into the calculator — the Belarusian and Russian tariffs are already inside.

What the water added to dilute manure costs per year: hauling, electricity, and the water itself.

TU BY 390449655.001-2017, EAEU declaration No. BY/112 11.01. TR010 000.00 23818
Certification is held by the manufacturer of the series, VitTechNasos LLC; the VTN series is built by NPO-Organika, the successor to that manufacturer.
How a VTN differs from a mass-produced pump
On the left are the manufacturer's passport figures of a mass-produced manure pump; we do not name it. The full six-parameter comparison lives on the page of the base VTN-1 model.
| Parameter | Mass-produced sewage pump from municipal services (manufacturer's passport) | VTN-1DU |
|---|---|---|
| Unit weight | Mass-produced pump (manufacturer's passport)1,150–1,300 kg | VTN-1DUup to 700 kg |
| Pumping distance | Mass-produced pump (manufacturer's passport)up to 500 m | VTN-1DUup to 2 km — four times further; depends on flow rate and pipeline diameter |
| Discharge lift | Mass-produced pump (manufacturer's passport)3 m, 5 m with an extension | VTN-1DUup to 13 m with an extension |
The left-hand column is the manufacturer's passports of mass-produced manure pumps sold in the CIS; the right-hand one gives our model's figures, which depend on the version and on the route.
Operating principle of the VTN-1DU pump
The VTN-1DU submersible centrifugal pump is the flagship of the series for viscous and contaminated media in large volumes and over long lines: manure and effluents with sediment travel from big collectors and lagoons to remote storage, fields and processing. Submersion from 0.5 to 10 m and a column from 1.5 to 3 m allow it to work in deep tanks, while the mixing radius of up to 7 m evens out the mass across the whole intake area — no separate mixer is needed even on a large lagoon.
The step up comes not from pushing the base design harder but from different hydraulics: an enlarged impeller — from 340 mm — runs at reduced 1000 rpm with a 22–50 kW electric motor; the discharge spigot is from 150 mm. The rest is the series' signature engineering: steel wetted parts and a cutting mechanism at the inlet shearing fibres and stalks. Through the pressure line the mass travels up to 2 km; the actual reach is set by flow rate, pipeline diameter, lift and moisture of the mass.

Installation and site preparation
- Installation is done by the manufacturer. Supply, installation and commissioning under a single contract: we deliver, install, start the equipment up and hand over a working station under an acceptance certificate. Replacing old equipment is possible — dismantling it is our job.
- What the customer prepares before the installers arrive: a concreted pad by the manure collector and a cleaned receiving tank. We send the requirements once the order is placed — for your own scheme.
- Power connection. The pump is connected to a 380–400 V supply through a control panel; the panel, the cable and the protective switchgear are part of the scope of supply agreed for the order.
- Servicing without a crane. To lift the pump for servicing, the station comes with a portal or a jib crane with a hoist — the pump is raised by your own people, no mobile crane required.
- The first start-up is carried out by our specialists during commissioning; the customer receives the operating manual and the servicing schedule.
VTN-1DU — frequently asked questions
Is the VTN-1DU just a more powerful VTN-1?
No — it has different hydraulics rather than a boosted base design: an impeller from 340 mm at 1000 rpm (the VTN-1 has 243 mm at 1500), a 22–50 kW drive, a spigot from 150 mm. Hence the highest capacity and submersion depth in the range; the highest head belongs to a separate version.
Are the capacity of up to 650 t/h and the head of up to 40 m one and the same version?
No: they are limits of different versions of the model. Send us your task parameters — we will select the specific version and state its working figures.
What tanks does the VTN-1DU suit?
Deep ones: submersion from 0.5 to 10 m, a pump column from 1.5 to 3 m. The installation opening is from 800×800 mm depending on the version.
Wouldn't two smaller pumps be a better deal?
Two pumps mean two installation openings, two power lines, two lifting devices and two service points. The VTN-1DU was built precisely so that a large manure collector is covered by one unit: up to 450 t/h even on viscous manure (85% moisture) and a mixing radius of up to 7 m. Send us the volume and route parameters and we will compare the options in the quote.
Who already runs a VTN-1DU?
SPK Rodina collective farm (Belynichi district, Mogilev region): thanks for the VTN-1DU and VTN-1 centrifugal pumps, ref. No. 184 of 1 April 2025. The letter is available on request with the quote.
How do I order a VTN-1DU?
Send your task parameters (volume, line, tank depth) via the form or by phone — we will select the version and prepare a quote. Price on request, terms are prepayment; repairs and service are handled by the factory itself in Vitebsk.
Price on request: the configuration is assembled for your site. Leave a request and an engineer will select the right version and quote the price.
