HECHT Technology offers a comprehensive range of powder handling equipment for the process industry. Our product range includes solutions such as endless liner systems for contamination-free bulk transfer and powder dosing systems for precise and safe powder feeding — engineered for pharmaceutical, chemical, food, and battery applications.
Pinch valves
Pinch valves (also known as hose valves) are flexible valves that regulate the flow of powders, granules or slurries by controlled compression of an elastic tube. This type of valve has no moving internal valves or metal sealing surfaces in contact with the product, thereby minimising wear, contamination and jamming.
Split butterfly valves
Components for bulk handling
HECHT components — standard & custom elements for bulk material handling
HECHT components (also designated as "Elements") are modular, high-performance parts for safe and hygienic bulk material processing — designed for pharmaceutical, chemical, and food applications where containment, precision, and regulatory compliance are non-negotiable.
What are HECHT components?
HECHT Elements are optimised subassemblies and interface components that integrate directly into new production line architectures or upgrades of existing installations. Each component is tested for airtightness, dust-free handling, and CIP/SIP compatibility — and can be exchanged in minutes without downtime.
Product categories
Containment & closing systems
- Continuous liners — Sterile disposable liners for drums, big bags, and intermediate bulk containers; fully closed system, zero product loss
- High containment closing systems — Pneumatic or manual sealing systems for closed powder transfer under negative pressure; OEB 1–5 certified
- Flex-couplings & disconnect systems — Quick couplers with integrated valve sealing; eliminates dust clouds at disconnection
Feeding & Dosing
- Filling heads — Permanently mounted filling spouts for precision dispensing; supports both powder and liquid
- Connection systems — Modular, stainless steel push-fit fittings and hose clamps for flexible system assembly; fully disassemblable for CIP
- Charging harnesses — Closed suction line systems for powder transport; antistatic, ATEX-compatible
Processing & transport
- Scale compensators — Pneumatic spring-load systems that compensate dynamic load changes in milling equipment; stabilises tolerances
- Delumper & screen graters — Fine lump-breaker with integrated sieving; prevents clogging in transport lines
- Suction shoes — Vacuum contact points for secure grip on drums/big bags; no packaging damage, suitable for ATEX zone 21
- Screw conveyors — Compact screw pumps for powders; variable speed, integrated shutoff
