HL Type Oil Lubrication Pump
Also sold as the HL Type Motor-Driven Lubrication Pump
The HL Type Motor-Driven Lubrication Pump is the higher-flow single-phase pump in the motor-driven oil range, rated 15 kgf/cm² with a maximum of 25 kgf/cm². Ordered with or without the pressure take-off mechanism, in a 2 L or 4 L reservoir.
How it works
The same gear-pump principle as the TZ at a wider volumetric flow rate, so one HL can serve a longer main line or a larger distributor group. Rated 15 kgf/cm², maximum 25 kgf/cm², volumetric flow rate 75% or better.
With the pressure take-off mechanism the pump forms a positive-displacement inspecting volumetric system, dosing oil to each point through a volumetric distributor. Without it, it forms a resist-type system, delivering oil in proportion to each point.
Level switch standard, pressure switch to order. Together they let the pump detect system pressure and oil level and integrate intermittence, operation and alarm.

How to read the order code
- Discharge capacity per minute
- 1 = 0–100 cc · 2 = 100–200 cc · 3 = 200–300 cc
- Number of motor poles
- 2 = 2P
- Timer module
- 0 = without dual-timer module · 1 = built-in dual-timer module
- Motor type
- 1 = single-phase 100 V · 2 = single-phase 220 V
- Reservoir volume
- 2 = 2 L · 4 = 4 L
- Pressure switch action pressure
- 00 = without pressure switch · 05 = 5 kgf/cm² · 10 = 10 kgf/cm²
- Pressure take-off mechanism
- X = built-in, for dosing distributors · T = without, for resist-type
- Suffixes
- D = level switch up is on (blank = down is on)
Before you order
- HL is single-phase only, 100 V or 200 V. For three-phase supply specify a TZ.
- The pressure take-off mechanism is built in at manufacture. State the distributor type on the order.
- Metal reservoirs are custom-made. Specify at time of order.
Warranty
One year against manufacturing defect from date of invoice.
How it pairs
The HL Type Oil Lubrication Pump is commonly specified alongside the RH3 Type Volumetric Distributor, the 34 Type Volumetric Distributor, the 35 Type Volumetric Distributor, the TCJ/TCZ Resist Type Distributor, the TK Adjustable Resist-Type Proportion Distributor, and the SD2 Type Progressive Grease Distributor. That is the same recommendation carried on its own datasheet, not a generic same-category suggestion.
Used on
Industry applications
Ways, ball screws and LM guides on machining centres, turning centres and routers: metered oil to every point, and a wireless handwheel for the setter.
Tie bars, toggle pins and platens on horizontal and vertical machines: oil or semi-fluid grease, metered per point and re-metered every cycle.
Step chains, sprockets and rollers on continuous-duty runs: oil proportioned to every point while the machine runs, so nobody has to reach into the truss.
