Why Choose This Pump?.
Hoffmann HP Piston Pump HL22B
- Its **22 L/min flow at 40 bar** makes it suitable for fire-fighting monitors, agricultural boom sprayers, or high-pressure wash systems.
- Dry-run protection means less risk of failure or damage when suction conditions are not ideal — a helpful safeguard in field settings.
- Compact weight (~8-9 kg) and good build materials make it mobile and relatively easy to integrate into diesel engine drives or PTO setups.
- Reputable brand and local South African availability of spares (Hoffmann Power).
Typical Applications & Use Cases.
Hoffmann HP Piston Pump HL22B
- Mounted on agricultural machinery or tractors for chemical/irrigation application (boom sprayers, orchard sprayers).
- Fire-fighting pump rigs or mobile fire units where a compact high-pressure pump is required.
- High-pressure cleaning or wash-down systems (truck wash bays, equipment wash-stations) where moderate flow but high pressure is needed.
- Water transfer applications where inlet conditions may vary and suction head may be limited, requiring dry-run robustness.
Pre-Purchase & Installation Checklist.
Hoffmann HP Piston Pump HL22B
- Drive source compatibility: Confirm whether you’re driving via engine, belt, PTO or electric motor; ensure RPM matching (HL22 series 800-950 rpm listed) and power available.
- Suction/inlet conditions: Maintain correct suction head or prime the pump; although dry-run tolerant, best service life when properly installed.
- Outlet piping & valves: Use pipe sizes that minimize pressure loss; include non-return and isolation valves to protect pump and system.
- Material compatibility: If pumping chemicals or agro-chemicals, confirm that pump head/plungers are compatible (some rigs may need special seals/materials beyond stock brass/stainless).
- Maintenance access: Even though durable, pumps of this type benefit from periodic inspection of seals, plungers, valve plate, belt/timing if used.
- Warranty & spares: Confirm local stock of spare parts (valve plate, seals, accessories) and warranty terms. Hoffmann listings indicate local dealer network.
