BW GA-SPAKv Electric Sampling Pump

Overview

The BW GA-SPAKv Electric Sampling Pump is a compact, intrinsically safe-compatible sampling interface engineered by BW Technologies (a Honeywell company) to extend the functionality of diffusion-based portable gas detectors. Designed and manufactured in Canada, the GA-SPAKv operates on the principle of active aspiration—drawing ambient air through a sampling line into the sensor chamber of compatible BW instruments such as the GasAlertMicroClip X3, Ventis MX4, or Solo series. This enables remote, non-intrusive gas monitoring in environments where direct instrument placement is impractical or hazardous—particularly during pre-entry assessment of confined spaces, pipeline integrity verification, ductwork inspection, and leak localization in industrial facilities. Its robust architecture supports continuous operation under variable thermal and humidity conditions while maintaining stable volumetric flow control critical for accurate sensor response time and calibration traceability.

Key Features

• Integrated hydrophobic membrane valve and particulate filter—prevents moisture ingress and particulate contamination of downstream sensors without compromising flow integrity
• Real-time diagnostic monitoring: audible (90 dB) and visual alarms for low sampling flow, low battery voltage, and internal system fault conditions
• Manual flow block test at startup—verifies pump priming, hose integrity, and suction performance prior to deployment
• Extended runtime: up to 30 hours on two standard AA alkaline or NiMH rechargeable cells—optimized for shift-long operations without field recharging
• Modular inlet compatibility: accepts both flexible 1/8″ ID sampling tubing and rigid 1/4″ OD probes (e.g., stainless steel or PTFE-lined), supporting custom probe configurations up to 15.2 m
• Low thermal mass housing and passive thermal regulation—enables reliable operation across –20 °C to +50 °C (NA mode) with minimal condensation risk in high-humidity environments

Sample Compatibility & Compliance

The GA-SPAKv is not a standalone gas analyzer but a certified peripheral device intended exclusively for integration with BW Technologies’ diffusion-type gas detection platforms. It complies with mechanical and electrical interface specifications defined in BW’s System Integration Guidelines (SIR-002 Rev. D). When used with ATEX/IECEx-certified BW detectors (e.g., Ventis MX4 with appropriate certification suffix), the complete assembly meets Zone 1/21 hazardous area requirements. The pump itself carries no intrinsic safety rating but is designed to operate only with approved BW host units that manage power delivery, fault isolation, and alarm routing. It supports regulatory workflows aligned with OSHA 1910.146 (Confined Space Entry), CSA Z1000-14 (Occupational Health and Safety Management), and EU Directive 2014/34/EU when deployed within validated gas detection protocols.

Software & Data Management

The GA-SPAKv operates autonomously without embedded firmware or wireless connectivity—it functions as a dedicated electromechanical subsystem synchronized via analog trigger signals from the host detector. All operational status data (flow interruption, battery depletion, error codes) are relayed directly to the host unit’s display and logged within its internal event memory. When paired with BW’s proprietary Docking Station (e.g., DSX-100) and Fleet Manager software, pump-related events—including runtime totals, alarm frequency, and calibration interval adherence—are aggregated into auditable reports compliant with GLP/GMP documentation standards and FDA 21 CFR Part 11 electronic record requirements (when configured with digital signature and audit trail modules).

Applications

• Pre-entry atmospheric verification in tanks, silos, manholes, and boiler chambers
• Continuous perimeter monitoring during hot work or excavation near buried utilities
• Remote sampling from elevated or inaccessible locations (e.g., flare stacks, HVAC ducts, chemical process headers)
• Leak detection and source localization using concentration gradient mapping across pipe networks
• Verification of ventilation effectiveness in enclosed workspaces prior to personnel re-entry
• Calibration gas delivery assurance during bump testing and full-scale calibration procedures

FAQ

Is the GA-SPAKv intrinsically safe on its own?
No—the GA-SPAKv lacks independent IS certification. It must be used only with BW-certified host detectors that provide proper energy limitation and fault containment.
Can it be used with non-BW gas detectors?
Not recommended. Mechanical, electrical, and communication interfaces are proprietary to BW’s ecosystem; third-party integration may compromise alarm reliability and void warranty.
What is the maximum allowable sampling line length for accurate response time?
For ≤15.2 m (50 ft), total transport delay remains within acceptable limits (≤45 s) for most toxic and combustible gases—per ISO 16000-23 and ASTM D5403 guidance on sampling lag compensation.
Does the pump require periodic recalibration?
No—its flow rate is factory-set and verified via pressure-drop testing against NIST-traceable flow standards; however, routine functional checks using the built-in flow block test are required before each use.
How does the hydrophobic filter affect maintenance intervals?
Under typical industrial conditions, the integrated hydrophobic membrane extends service life between filter replacements to ≥6 months; replacement kits (BW P/N SPK-FILTR) are available separately.
