Semi-automatic filling machine SP2

drumIBCpail

Product overview
The SP2 is a compact semi-automatic filling line for containers handled on pallets, with integrated infeed and outfeed conveyors. Pallets are transported into the filling station so the operator only aligns and fills containers; filled pallets exit automatically. Typical throughput: up to 65 drums/hour or 15 IBCs/hour. Container range: 20–1,500 L (down to 0.2 L with an additional scale).

Suitable containers

• Drums, kegs, pails, canisters and IBCs placed on a pallet

How it works

• Choose filling recipe and target net weight on the operator panel.
• Adjust filling height without tools (550 mm servo height adjustment).
• Place pallet of empty containers on the infeed conveyor.
• Operator authorises pallet advance; pallet moves automatically into the filling station.
• Operator releases and positions the filling head; the head locks on release.
• The system tares automatically and fills to net weight; alignment and filling repeat for each container on the pallet.
• Operator commands discharge; the full pallet moves out and the next pallet advances.
• Full pallets are collected at the end of the line.

Filling modes and assemblies
Two stainless-steel filling assemblies are available (AISI 304 structure, nozzle AISI 316L standard). The immersion assembly can operate under-bunghole or from the bottom, selectable by recipe.

• Under-bunghole filling: nozzle enters just inside the container and fills from that position; suited to non-foaming, non-flammable, dense or viscous products.
• Immersion filling: nozzle reaches container bottom; suitable for foaming, flammable or explosive products. Immersion recipes may fill while lifting, from the bottom, or under-bunghole.

Machine architecture
Self-supporting structure with a vertical column carrying the filling head. The filling station is above the conveyor so pallet infeed, positioning and discharge occur without a pallet truck and without the operator entering the filling area. Weighing is performed by a weighing conveyor integrated into machine control.

Control and software (AiCROVFill®)
AiCROVFill® provides recipe-based operation, misalignment control (head retracts and waits if nozzle meets resistance), final weight control and automatic top-up, submerged-lance volume compensation and learning/compensation for post-cutoff flow—ensuring repeatable weight filling in challenging products and conditions.

Inert gas filling (optional)
Optional inerting is controlled by recipe (inert before opening, during fill, after weight reached, or any combination). Nozzle includes a gas passage actuated from the main cabinet. Inerting reduces oxygen exposure for product quality or to eliminate ignition risk; nitrogen is commonly used.

Built from standard industrial parts
SP2 is assembled from widely available industrial components for control, pneumatics, sensors and weighing elements. No proprietary electronics in the control chain, facilitating local sourcing of spare parts and maintenance.

Safety and compliance
Designed and manufactured in Europe to relevant machinery safety legislation and supplied with CE marking. Design follows harmonised standards (EN ISO 12100, EN ISO 13849-1, EN 60204-1, EN ISO 13850). Safety features: emergency stop cutting power and pneumatic pressure, conveyors stop, pallet movement only under panel authorisation, head braked by default, passive nozzle lock, and safe behaviour on failure. Explosion-proof versions available to required certification schemes (e.g., ATEX, IECEx, NEC) for Zone 1 or Zone 2 installations.

Typical applications and flexibility
Applicable across chemical, petrochemical, lubricant, detergent and food-related liquid industries where weight filling is required. Handles viscous, sticky, foaming, flammable or corrosive liquids. Changing product or container generally requires only a nozzle change and recipe selection; nozzle is interchangeable without modifying the filling head.
