System Compatibility

Proportional Valves: Compatible with all standard resistance meter units (e.g., CZA, CZB, FJB, HJB series).

System Pressure: Delivers stable 1.0–1.5 MPa operating pressure to drive proportional flow resistance across all lubrication points.

Automatic Decompression: Built-in relief valve drops line pressure below 0.05 MPa after each cycle, ensuring instant reset of connected meter units.

Flow Distribution: Oil volume per point is governed strictly by individual meter unit orifice ratings, independent of pump pressure settings.

Tubing Standards: Standard M10×1 outlet ports connect directly to Ø4mm or Ø6mm nylon and copper lines.

Product Features

Precision Alloy Gear Pump: High-carbon heat-treated steel pump core prevents output pressure drop during continuous operation.

Durable Oil Reservoir: UV and chemical-resistant transparent resin tank, with optional heavy-duty steel tanks for high-vibration machinery.

Dual Filtration Protection: Built-in fill-port basket filter and internal suction strainer prevent micro-orifice clogging in distribution valves.

Integrated Safety Relief: Internal pressure relief valve protects system components against over-pressurization.

Automatic Low-Level Detection: Magnetic float switch provides dry-contact signals to prevent dry running and motor burnout.

FAQ

Q: How does a resistance pump differ from a progressive pump?

A: Resistance pumps use proportional meter units operating at 1.0–1.5 MPa and require automatic line decompression (<0.05 MPa) between cycles to reset valves. Progressive pumps use volumetric divider blocks operating sequentially under much higher pressures (10–25 MPa).

Q: How do I select the correct meter unit sizes?

A: Oil volume per point is determined by the specific orifice rating of each meter unit (e.g., CZA/CZB), not by adjusting pump pressure. Ensure total system demand does not exceed pump capacity (100–200 cc/min).

Q: What is the maximum recommended main pipeline length?

A: Up to 15 meters using Ø4mm or Ø6mm tubing to ensure rapid pressure build-up and prompt decompression (<0.05 MPa).

Q: What if system pressure fails to drop below 0.05 MPa after stopping?

A: Check for trapped air in the main line and bleed the furthest manifold. If air is absent, clean the internal suction filter and relief valve mechanism.

Q: Can this pump be controlled directly by a host machine PLC?

A: Yes. Non-timer configurations allow host PLCs to power the motor and process dry-contact signals from the low-level float switch directly.

Q: Are replacement parts available separately?

A: Yes. Replacement reservoirs, 80-mesh strainers, float switches, and motors are stocked for maintenance.

Q: Are Imperial / NPT port adapters available?

A: Yes. Factory-installed brass adapters for PT 1/8 or NPT 1/8 threads can be supplied to match regional piping standards.

Q: What electrical protection is recommended?

A: Fast-acting fuses or thermal overload relays matched to the motor voltage (110V/220V/380V AC or 24V DC) to protect against voltage spikes or motor jams.
