About the VTN-1D pump
VTN-1D is a version of the base model of the series for viscous and contaminated media, with the pump end extended to 3 m: intake from deep pits and sunken tanks that a standard column cannot reach. The hydraulics stay standard — capacity up to 300 t/h on liquid manure, head up to 24 m, mixing in the intake area within a radius of up to 5 m. Like the whole VTN series, this version takes raw manure at natural moisture from 75% with no water dilution. Below three metres, and at the maximum volumes of the series, the job goes to the VTN-1DU flagship; for a standard pit the base VTN-1 is enough, and where there is no power grid there is the VTN-1MT driven by a tractor PTO.
Key features:
- A 3 m pump end — intake from a depth of up to 3 m in pits and sunken tanks where a standard column falls short
- The hydraulics of the base model, unchanged: capacity up to 300 t/h on liquid manure and up to 200 t/h on viscous manure (85% moisture), head up to 24 m
- Manure at natural moisture from 75% — no dilution water to add, and no growth in the volumes to store and haul
- Cutting mechanism at the inlet: fibres are not a limit, and solids pass through at sizes up to 30 mm
- Installation opening from 600×600 mm and a spigot for a pressure hose with inner Ø from 100 mm — the unit fits the same hatch as the base model
Applications:
- Livestock complexes and farms: pig and cattle farms with deep manure collectors — intake from pits and sunken tanks, delivery to vehicles, storage facilities and processing.
- Municipal services and wastewater treatment: effluents and sludge with fibrous inclusions from sunken chambers and receiving tanks.
- Industry and construction: process effluents with sediment, pumping contaminated water out of deep sumps and excavations.
The VTN-1D is chosen when the tank is deeper than standard while the volumes stay the same. A shallower pit needs only the base VTN-1; homogenization in a compact unit calls for the VTN-1M pump-mixer; a site without a power grid takes the tractor-driven VTN-1MT; a large complex with a deep tank and a long line takes the VTN-1DU flagship.

Deeper than the base model, short of the flagship
When the standard submersion of a VTN-1 (up to 1.5 m) is not enough and the flagship would be overkill for the job, the answer is the VTN-1D: the same base pump with a pump end extended to 3 m. Hydraulics, drive and servicing are those of the VTN-1, which has been running on farms since 2015; the single difference is that it reaches the bottom of a deep pit.
The depth of the pit changes nothing about the main point: like the whole series, the 1D moves manure from 75% moisture — without the dilution water that would then have to be stored and hauled. What that means in money for your own herd is what the calculator works out (Belarus and Russia).

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.
Where it sits in the range
Intake from a depth of up to 3 m in pits and sunken tanks; capacity up to 300 t/h on liquid manure and up to 200 t/h on viscous manure (85% moisture), head up to 24 m — the figures of the base model (limits of different operating modes; the duty point is selected when you order). If the tank is deeper than three metres, or you need the maximum volumes of the series, look at the VTN-1DU flagship (submersion from 0.5 to 10 m); for a standard pit the VTN-1 is enough.
Working principle of the VTN-1D pump
The VTN-1D submersible centrifugal pump works in viscous and contaminated media — manure of reduced moisture, effluents with sediment and fibrous inclusions. The version differs in one thing: the pump end is extended to 3 m, so the pump reaches the bottom of pits and sunken tanks where a standard column falls short. In the intake area the mass is evened out within a radius of up to 5 m, and from there it goes into the pressure line — up to 1 km depending on flow rate, pipeline diameter, lift and moisture of the mass.
Everything else on this version is standard: hydraulics, drive and the service routine are those of the VTN-1, so spare parts and servicing are shared by both machines. The wetted parts are steel and built for viscous and abrasive media; a cutting mechanism at the inlet shears straw and long-stemmed inclusions, so mesh filters and a separate shredder are not needed on the line. Lubrication is forced and not tied to any particular grease grade. The detailed design is described in the product passport.

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-1D — frequently asked questions
How does the VTN-1D differ from the VTN-1?
Only in the pump end: on the 1D it is extended to 3 m, for intake from deep pits and tanks. Capacity, drive and servicing are those of the base model; the detailed design is in the product passport.
When do I need a VTN-1D and when a VTN-1DU?
If the job is to reach deeper than the standard 1.5 m at ordinary volumes, the 1D is enough (submersion up to 3 m). The VTN-1DU flagship is for large complexes: submersion from 0.5 to 10 m and the highest capacity and head in the series.
How do I order a VTN-1D?
Send us the depth of the tank and the parameters of the line — we will confirm the configuration and name the price (on request). We build to the conditions of your farm; 12-month warranty, manufacturer's service 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.
