25B Liquid Pump
The Nordson 25B Liquid Pump is a versatile, air-operated hydraulic pump for heated or unheated spray systems and fluid delivery applications.
Overview
- Positive-displacement, demand-type pump
- Available in 2:1, 4:1, 16:1, and 27:1 fluid-to-air ratios to meet a variety of high-pressure, airless and low-pressure, higher-volume applications
- Reciprocating plunger and packing design reduces pump wear and maintenance costs
- Wide selection of standard packing materials are available for use with a variety of coating formulations
- Hard-chrome wear surfaces for long life using abrasive coatings
- Standard-type U packing glands offer excellent abrasion resistance with zero water absorption for much longer packing life
- Large, stainless-steel ball checks provide smooth fluid delivery with high-viscosity coating materials
- Large, enclosed solvent chamber lubricates plunger and increases upper packing life
Features and Benefits
Reciprocating plunger and packing design — reduces pump wear and maintenance costs.
Wide selection of “standard” packing materials — for use with a variety of coating formulations.
Hard-chrome wear surfaces — for long life using abrasive coatings.
Mounting versatility — wall, drum, five-gallon pail or dolly mounting accommodates varying application requirements.
Standard type U packing glands — offer excellent abrasion resistance with zero water absorption for much longer packing life.
Large, stainless-steel ball checks — provide smooth fluid delivery with high-viscosity coating materials.
Large, enclosed solvent chamber — lubricates plunger and increases upper packing life.
Mechanical air valve — provides reliable, fast cycling action to minimize pressure fluctuations for a more uniform spray pattern.
Sheet metal cover — protects pump from the hazards of normal industrial environments.
Patented ScoreGuard precision-ground, hard-chrome hydraulic plunger — ensures long service life.
Air-operated pump — can be safely used in hazardous locations with solvent-based coatings.
Self-adjusting hydraulic packing glands — need no maintenance throughout their life and cannot be overtightened or neglected.
