Burkle MTD5601 Series Stainless Steel Drum Pumps

Overview

The Burkle MTD5601 Series Stainless Steel Drum Pumps are engineered for safe, reliable, and compliant transfer of flammable and combustible liquids from standard 200 L (55 gal) drums and intermediate bulk containers (IBCs). Designed in accordance with ATEX Directive 2014/34/EU for equipment intended for use in potentially explosive atmospheres, these pumps operate within Zone 0 — the most stringent classification for continuous presence of ignitable gas/vapor mixtures. The core principle relies on positive displacement via a manually or electrically driven impeller housed within an electrically conductive 316 stainless steel body, ensuring full static dissipation when properly grounded. This architecture eliminates spark generation during operation and meets critical safety requirements for hydrocarbon, solvent, and chemical handling in laboratory, refinery, and quality control environments.

Key Features

• ATEX-certified for Zone 0 operation — certified per EN IEC 60079-0 and EN IEC 60079-11 for intrinsic safety and increased safety (Ex ia IIC T4 Ga)
• Electrically conductive 316 stainless steel construction — fully grounded path from pump head to discharge nozzle
• Chemically resistant PTFE sealing system — non-lubricated, maintenance-free diaphragm and gasket set with >10,000-cycle service life under typical lab usage
• Modular design with interchangeable discharge assemblies — includes NW8 (DIN 2817) stainless steel ball valve nozzle (ID 12.8 mm) and optional PTFE-lined discharge tube (1.5 m, detachable, conductive)
• Three immersion depth variants (360 mm, 570 mm, 910 mm) supporting drum heights from 475 mm to 1030 mm — optimized flow rates between 9–22 L/min depending on viscosity and lift height
• Integrated grounding lug and compliance-ready documentation package — includes EU Declaration of Conformity, ATEX certificate copy, and installation grounding instructions

Sample Compatibility & Compliance

These pumps are validated for use with Class I, Group C & D liquids per NFPA 30 and OSHA 1910.106, including gasoline, diesel, kerosene, acetone, ethanol, toluene, and other low-conductivity organic solvents. All wetted parts comply with FDA 21 CFR §177.1550 for repeated food-contact applications (when specified), and meet REACH SVHC and RoHS 2011/65/EU material restrictions. The pump assembly supports GLP/GMP-aligned workflows through traceable serial-numbered components and calibration-compatible mounting interfaces. No modification is required to satisfy ISO 8573-1 (compressed air purity) when used with pneumatic drive options.

Software & Data Management

While the MTD5601 series is a mechanical/electromechanical device without embedded firmware, its integration into automated lab infrastructure is supported via standardized analog 4–20 mA flow feedback output (on motorized variants) and dry-contact run-status signaling. Optional digital interface modules enable Modbus RTU communication for integration with LIMS, SCADA, or MES platforms. Audit trails for pump usage—including runtime hours, total volume dispensed (via external flow meter pairing), and grounding verification logs—can be maintained in alignment with FDA 21 CFR Part 11 requirements when deployed with validated electronic record systems.

Applications

• Quality control laboratories in petroleum, petrochemical, and lubricant manufacturing — precise sampling and transfer of reference fuels, base oils, and additive concentrates
• HSE-critical operations in upstream and midstream facilities — drum unloading under strict ignition-risk protocols
• Regulatory testing labs performing ASTM D93 (Pensky-Martens flash point), ASTM D445 (kinematic viscosity), and ISO 3104 — contamination-free fluid handling prior to analysis
• Research institutions handling novel biofuels and synthetic hydrocarbons — compatibility with high-purity, low-sulfur, and oxygenated blends
• Contract testing organizations requiring auditable, repeatable liquid dispensing across multi-client sample sets

FAQ

Is grounding mandatory for safe operation?
Yes. A verified ground resistance ≤10 Ω must be established between the pump body and facility earth before initiating any transfer of flammable liquids.
Can this pump handle viscous fluids such as gear oil or transformer oil?
Performance is optimized for kinematic viscosities up to 150 mm²/s at 40 °C; higher viscosities require reduced immersion depth and lower flow rate expectations.
What certifications accompany each unit?
Each pump ships with ATEX Certificate of Conformity, EU Declaration of Conformity, material test reports (EN 10204 3.1), and grounding verification checklist.
Are replacement PTFE gaskets available as consumables?
Yes — OEM PTFE gasket kits (part no. GSK-MTD5601) are stocked and supplied with batch-specific CoA documentation.
Does the pump support sterile or cleanroom applications?
Not inherently — however, electropolished 316L variants and VHP-compatible surface finishes are available under custom order (lead time applies).
