Murzan DUS-50M sanitary drum unloading system stainless steel designed to empty 55-gallon (≈200 L) drums

The Murzan DUS-50M is a sanitary drum unloading system designed to empty 55-gallon (≈200 L) drums containing very viscous products such as food pastes, creams, gels, or cosmetic compounds.

Murzan DUS-50M – Overview

• Type: Drum Unloading System (DUS)

• Manufacturer: Murzan Inc.

• Application: Pumping thick products out of drums in a hygienic way

• Typical industries: Food processing, cosmetics, pharmaceuticals.

Main Features

• Air-operated double diaphragm pump (Murzan PI-50 series).

• Stainless-steel sanitary construction (typically 304/316).

• Follower plate with scraper ring that wipes the drum walls while pumping.

• Pneumatic ram lowers the pump into the drum.

• Portable frame with casters and often a drum ramp or roller conveyor.

• Sanitary tri-clamp connections for product lines.

Performance

• Designed for very high-viscosity products (e.g., peanut butter, tomato paste, creams).

• Handles viscosities up to ~150,000 cP depending on configuration.

• Capacity: up to about 60 gallons per minute (≈227 L/min) depending on product and system setup.

How It Works

1. A 55-gallon drum is positioned under the system.

2. The pneumatic ram lowers the pump and follower plate onto the product surface.

3. The diaphragm pump removes the product, while the follower plate wipes the drum walls.

4. When empty, air cylinders lift the pump assembly out of the drum.

Typical Products Pumped

• Tomato paste

• Peanut butter

• Chocolate or fudge

• Cream cheese

• Cosmetic creams or lotions

• Pharmaceutical gels and ointments.

Key advantage: It empties drums almost completely without manual scooping, maintaining hygiene and minimizing product loss.
