VAV Aandrijvingen (VAV Conveyor Components) — Bulk Handling Chains, Elevator Parts & Screws
Industrial conveyor chains (WH-series, VO-chain, DIN 8165/8167), sprockets, elevator buckets and belts, and screw conveyor spirals up to 3,000 mm from VAV Aandrijvingen B.V.
Drop Forged & DIN 8165 / 8167 Chains
Heat-treated drop forged chains and double drag link chains per DIN 8165 (FV) and DIN 8167 (M) handle abrasive bulk loads. Links combine outer and inner plates, bushes, and pins for heavy-duty drag conveyors. Used in animal feed, minerals, asphalt, concrete, and recycling plants.
- Forged heat-treated alloy steel
- DIN 8165 (FV) & DIN 8167 (M) standards
- Outer/inner links, bushes, and pins
- L-, U-, or welded T-shape scrapers
WH-Series Welded Steel Conveyor Chains
Welded steel offset sidebar chains cover WH78, WH82, WH106, WH110, WH111, WH124, WH124H, WH132, WH150, WH155, and WH157. Pitches span 66.27 to 153.67 mm with breaking loads from 117.5 to 902.0 kN. Heat-treated pins and bushings resist dust, abrasion, and shock loads.
- Models WH78 through WH157
- Pitch range 66.27 to 153.67 mm
- Breaking load 117.5 to 902.0 kN
- Heat-treated pins and bushings
VO-Chain Welded Fork-Link Scraper Chains
VO-chain uses welded sheet-metal fork links assembled with a pin and Allen bolt for quick service. Standard widths are 260, 360, 460, and 560 mm at 150 mm pitch and breaking loads up to 170 kN. Welded curved scrapers support plastic cleaning sheets and return boxes.
- 150 mm pitch; widths 260 to 560 mm
- Breaking loads: 110, 130, or 170 kN
- Pin and Allen bolt disassembly
- Optional cleaning sheets and return boxes
Sprockets, Segments & Plastic Scrapers
Sprockets include body wheels with replaceable tooth segments for forged chains (102–200 mm pitch) and split DIN wheels (63–160 mm pitch). Flights come in bent or welded steel and Nylon, Fiberglass, FDA, Detectable, or Zytel (+80/+110 C) plastics. Split designs speed up maintenance.
- Replaceable tooth segments (102–200 mm)
- Split sprockets & return wheels (63–160 mm)
- Nylon, Fiberglass, FDA, Detectable (-20/+70 C)
- High-temp Zytel flights (+80/+110 C)
Elevator Buckets, Belts, Bolts & Pulleys
Bucket elevator parts cover rubber and PVC belting plus pressed or welded buckets in S235, wear-resistant steel, stainless steel, and plastics. Hardware includes DIN 15237 bucket bolts and belt fasteners in mild steel, bronze, or stainless steel. Open and closed pulleys match belt ratings.
- Buckets in S235, wear-resistant, stainless, plastic
- Rubber and PVC elevator belting
- DIN 15237 cup-head bucket bolts
- Open and closed elevator pulleys
Screw Segments, Spirals & Hanger Bearings
Screw conveyor parts cover screw segments, endless spirals, shaftless spirals, mix spirals, and adjustable hanging bearings. Mix spirals reach 3,000 mm diameter (larger in 180 or 90 degree segments) in S235JRG2, S355JRG3, Hardox 400, and 304/316L/316Ti. Fits horizontal, inclined, and vertical runs.
- Screw segments, endless & shaftless spirals
- Mix spirals up to 3,000 mm outer diameter
- S235JRG2, S355JRG3, Hardox 400 steels
- Stainless 1.4301/1.4404/1.4571 & bearings
Bulk-Handling Conveyor Chains, Sprockets & Flights
Founded in 1973 in Rijnsburg, the Netherlands, with over 5,400 m2 of warehouse capacity, VAV Aandrijvingen B.V. (VAV Conveyor Components and Solutions) engineers and supplies heavy-duty components for animal feed, minerals, recycling, asphalt, and concrete bulk handling.
Chain solutions span heat-treated drop forged chains, double drag link chains per DIN 8165 (FV) and DIN 8167 (M), Allen-bolt VO-chains (260–560 mm width, up to 170 kN), and WH78–WH157 welded steel offset sidebar chains (66.27–153.67 mm pitch, up to 902.0 kN).
Body wheels with replaceable tooth segments and split DIN sprockets simplify maintenance alongside Nylon, FDA, Detectable, and Zytel (+80/+110 C) flights.
Bucket Elevator Components, Pulley Ratios & ATEX Options
Elevator components include rubber and PVC belting paired with pressed or welded buckets in S235 carbon steel, wear-resistant steel, stainless steel, and polymers, secured with DIN 15237 cup-head bolts and steel, bronze, or stainless belt fasteners.
Minimum recommended pulley diameters follow belt breaking strength: 315 mm for 400 kg/cm2, 400 mm for 500 kg/cm2, 500 mm for 630 kg/cm2, 630 mm for 800 kg/cm2, 800 mm for 1000 kg/cm2, and 1000 mm for 1250 kg/cm2.
Plastic elevator buckets eliminate steel-on-steel contact during misalignment for ATEX environments and reduce sticking with cohesive bulk solids.
Screw Conveyor Flights up to 3,000 mm & Alloy Selection
For horizontal, inclined, and vertical screw conveyors, VAV Aandrijvingen provides screw segments, endless cold-rolled spirals, shaftless spirals, mix spirals, and adjustable hanging bearings.
Custom mix spirals are produced up to 3,000 mm outer diameter (or larger in 180-degree and 90-degree segments) from S235JRG2, S355JRG3, Hardox 400, and stainless steel grades 1.4301 (304), 1.4401 (316), 1.4404 (316L), and 1.4571 (316Ti).
Technicians verify pitch, hand of helix, capacity, and bulk material abrasiveness before manufacture.
