32mm Head Vacuum Sampling Pumps (VSPG & VACFAST)

Taking unpolluted fluid samples is vital for effective oil analysis and preventive maintenance. Our 32mm Head Vacuum Sampling Pumps—commonly known as "thief pumps"—allow you to draw fluid directly from tanks, sumps, and systems into a sample bottle without contaminating the pump body or surrounding media .

Both models utilize standard $3/16"$ to $5/16"$ sampling tubing and feature a 32mm thread neck designed to fit compatible 32mm sampling bottles and adapters directly .

Model Options:

• VSPG32 (Standard / Entry-Level):
  • Construction: Lightweight glass-reinforced polyamide (GPA) cylinder, piston rod, and thread with a acetal homopolymer (POM) head .
  • Features: Full plastic construction offering solid chemical resistance against oils, greases, and aliphatic hydrocarbons . Fitted with nitrile O-rings as standard (Viton available upon request) .
  • Best For: Routine field sampling, lightweight toolkits, and general industrial oil analysis .
• VACFAST32 (Mid-Range / Heavy-Duty):
  • Construction: Brushed aluminum outer casing for enhanced structural rigidity, combined with a durable GPA drive assembly and POM pump head .
  • Features: Increased impact resistance for harsh work environments while retaining lightweight portability . Standard nitrile seals with optional Viton upgrades .
  • Best For: Demanding industrial sites, mobile service engineers, and high-frequency sampling tasks .
