Semi Automatic Weighing Filling Machine

This semi automatic weighing filling machine in the 10-50 kg range is a one-operator drum-filling station that uses a load cell to measure the actual mass of the product in the drum. It is the standard workhorse for paint, detergent, lubricant, edible oil, and chemical plants that fill open-mouth metal drums and plastic pails. The machine ships with a load-cell weighing head, switchable 380V / 220V power, and a pump-free architecture that lets the customer reuse a local chemical pump. Verified output is 60-240 drums per hour, and the all-in CIF price lands in the USD 4,000 – 7,000 band — roughly 5-8× cheaper than equivalent European all-in-one drum fillers.

What Is a Semi Automatic Weighing Filling Machine?

A semi automatic weighing filling machine is a one-operator drum-filling station in which an empty drum is placed on a platform by hand, the machine fills the drum to a preset weight using a load cell, and the operator removes the sealed drum. Compared with a volumetric filler (which counts piston strokes), a weighing filler measures the actual mass in the drum, so it stays accurate when the product density shifts with temperature, batch variation, or pump wear.

For a 10-50 kg range, the semi-automatic class beats both the manual stopcock (too slow, too inaccurate) and the fully automatic rotary filler (too expensive for batches under 1,000 drums per day). It is the right capital expense for a plant producing 200-2,000 drums per 8-hour shift.

Common Applications & Industries of Barrel Filling Machine

The 10-50kg semi automatic weighing filling machine is used in five distinct industries, each with its own drum size, viscosity, and accuracy requirement. The matrix below maps the typical configuration for each.

How to Choose the Right 10-50kg Barrel Filler?

A drum-filling line is a 10-year capital decision, so the right machine needs to match the product, the factory, and the local grid. The 6-point checklist below covers what our application engineers ask during a sample-shipment test in our Zhengzhou workshop.

1. Match the filling range to your drum size — a 10-50kg semi automatic weighing filling machine covers 10L, 20L, 25L, 50L in one unit. If you only ever fill 200L IBCs, look at the 200L IBC tote filler instead. If you need 1-5kg retail or sample packs, this machine is too large.
2. Check the power grid compatibility — the precision weighing filling machine is switchable 380V / 220V (50/60Hz), which covers Egypt, Saudi Arabia, Indonesia, the Philippines, and most of West Africa. If your site has only single-phase 110V (some Brazilian or rural-African sites), you need a step-up transformer or a different model.
3. Match the pump to the product viscosity — for thin oils (50-500 cP) use a gear pump; for paste-like paint (500-5,000 cP) use a pneumatic diaphragm or sanitary lobe pump; for volatile solvents (alcohol, acetone) use an explosion-proof ATEX pump. This type of weighing filling machine is pump-free, so this decision stays on the buyer’s side.
4. Verify the accuracy class against the product value — for water or low-cost liquids, ±1% (volumetric) is fine. For paint, oil, or any product above USD 1/kg, ±0.2% (weighing) saves more in give-away than the price difference between the two machines in under 6 months.
5. Confirm the local service footprint — the machine ships with a 12-month warranty and lifetime remote video support. For on-site commissioning, our engineers can fly to the customer site in under 36 hours.
6. Plan for format changeover time — switching from a 10L sample pack to a 25L drum on the semi automatic weighing filling machine is a touch-screen recipe selection and a 45-second drum-size changeover. A manual stopcock line takes 15-25 minutes for the same change. If you produce 5+ SKUs, this single feature covers the price difference in a year.

Price, ROI & What Buyers Say

The machine is sold pump-free by design; a matching local chemical pump is typically USD 800 – 3,000 depending on material and ATEX rating, and the customer can source it locally to keep a single spare-parts inventory. See the breakdown below for the all-in landed cost in a MENA or Southeast Asian port.

All-in landed cost breakdown

On the ROI side, a paint factory that previously hand-filled 130 drums per shift with 2.6% give-away will typically see a 3-4× output jump and a 2-percentage-point give-away reduction. On a 25 kg paint drum priced at USD 8 wholesale, 2% give-away recovery is USD 0.16 per drum; across 8,000 drums per month, that is USD 1,280 saved every month in raw material alone, not counting labour. With the all-in landed cost now between USD 5,500 and 10,300, the full investment is recovered in 2-4 months — substantially faster than the 4-6 month payback at the old USD 15,000-21,000 price band — and matches the verified 4.5-month ROI from the Nile Coatings Co. case.

“The pump-free design let us keep our locally-serviced chemical pump, which means one fewer spare-parts inventory. The weighing precision alone saves us around USD 9,000 of raw material every month, and we have already signed the three Libyan buyers we turned away in 2025. Engineer Zhang Wei arrived the same day we cleared customs, and commissioning was finished in two and a half days.”

— Mr. Ahmed Hassan, Founder & Managing Director, Nile Coatings Co., 6th of October City, Giza, Egypt

“The whole Shuliy 4-machine line plugged into a single 220V socket — that alone saved us a €14,000 electrical upgrade. If the machine had been available with the same single-phase compatibility at the time, we would have chosen it for the emulsion-paint line in our Lyon facility.”

— Mr. Pierre Leblanc, Founder & Managing Director, InsectPro Bretagne SAS, Cesson-Sévigné, Rennes, Brittany, France
