Engineered Solutions for Safe & Controlled Powder Transfer

At Mark Maker Engineering, we design and provide safe transfer solutions for the controlled movement of pharmaceutical powders and materials between process equipment.

Our transfer systems are developed to support both continuous powder transfer and intermediate powder transfer, helping maintain controlled material flow while reducing manual handling, product exposure and the risk of cross-contamination.

Split Butterfly Valve (SBV)

Split Butterfly Valve systems provide a contained connection between two process components, allowing material transfer while maintaining complete containment. Particularly suited for high-potency APIs and cross-contamination sensitive powders.

Available Valve Configurations
Manual SBV (100–250mm) Automated Pneumatic SBV Extraction Shroud SBV
  • Active valve mounted to process vessel docks with passive valve on IPC bin
  • Mating discs lock face-to-face, ensuring product never contacts external surfaces
  • Optional vacuum extraction ring reducing airborne dust below nanogram levels
  • Sanitary SS 316L metallurgy with FDA-approved EPDM / silicone elastomeric seals
STAGE 05 Automated Docking
Powder Transfer System (PTS)
Inflatable Seal Dust-Tight Docking

Powder Transfer System (PTS)

Automated pneumatic docking stations clamp receiving ports to discharging IPC bins or blender discharge valves, inflating an elastomeric seal to ensure 100% dust-tight containment during gravity drop.

Available Docking Systems
Powder Transfer System (PTS) → Pneumatic Lift & Seal Collar Blender Charge Station Tablet Press Docking Unit
  • Pneumatic lift cylinders raising the docking head to firmly mate with container flange
  • Inflatable silicone seal expanding to form a hermetic, pressure-tight barrier

  • Stackable framework with forklift guides and anti-static cleanroom castor wheels
  • Zero-dead-leg silicone butterfly valve with sanitary quick-release triclamp

Material Flow Architecture

Integrated Powder Transfer Systems

Our transfer solutions are engineered around the complete process rather than treating material transfer as a standalone operation.

A typical integrated process connects:
Material Preparation → Sifting → Granulation → Drying → Blending → Milling → Coating with controlled transfer interfaces between individual process stages.

Safe Transfer. Controlled Process. Reduced Exposure. We connect pharmaceutical equipment to create a safer and more efficient material-flow pathway across the plant.

01

Zero Cleanroom Dust Release

Hermetic docking ports and closed vacuum pipelines prevent powder plumes, keeping cleanroom airborne particulate well within ISO class limits.

02

Ergonomic & Safe Operation

LPD lifters and tippers eliminate manual heavy drum handling, reducing operator strain and preventing repetitive injury risks.

03

Containment Integration Ready

Transfer technologies interface seamlessly with barrier isolators, gloveboxes, and RABS using Split Butterfly Valves and RTP connections.

04

Sanitary CIP / WIP Cleanability

Crevice-free SS 316L contact metallurgy with quick-release triclamps and integrated wash-in-place ports ensuring rapid turnaround.

Core Standards

Engineered for Transfer Excellence

Our transfer equipment is designed with operator safety and contamination control at the forefront, complying with international cGMP and OSHA standards.

Zero Dust Emission Standards

Sealed flow paths prevent powder emissions, protecting operators and preventing cross-contamination between adjacent processing areas.

SS 316L Contact Metallurgy

Product contact surfaces crafted from SS 316L with Ra < 0.4 µm mirror finish, ensuring high flowability and zero residue adhesion.

Hydraulic & Mechanical Safety Arrestors

Dual-redundant hydraulic velocity fuses and mechanical anti-fall ratchet pawls preventing container descent under any power loss.

Inflatable Gasket Docking

Pneumatic silicone seals expanding to create airtight connections during charging into RMG, FBD, blenders, and tablet presses.

Active-Passive Docking Interlocks

Mechanical keys prevent valve rotation unless the active and passive halves are fully coupled and hermetically clamped.

cGMP Cleanroom Shrouds

Full stainless steel shrouds covering all motor drives, hydraulic power packs, and chains, meeting Grade C and Grade B cleanroom standards.

Structural Load Verification

Every lifting system undergoes 125% static and dynamic load testing with deflection verification prior to factory acceptance certification.

Full Validation Package (DQ/IQ/OQ)

Turnkey qualification documentation covering mechanical tolerances, limit switch interlocks, hydraulic schematics, and material test reports.

Application Engineering

Built Around Your Material & Facility Layout

There is no single transfer technology suitable for every pharmaceutical process. The appropriate system depends on the material characteristics, process sequence, batch size, equipment arrangement and containment requirements.

Mark Maker Engineering develops transfer solutions based on actual process and equipment interface requirements, with careful consideration for elevation, bin geometry, operator safety, and automation.
