Name: TZ Type Oil Lubrication Pump
Brand: AMAG CNC Technology

The TZ Type Motor-Driven Lubrication Pump is the general-purpose motor-driven oil pump in the range, available on single-phase and three-phase supply. Supplied in 2L and 4L high-strength plastic reservoirs (metal reservoir custom-made on request), with three timer configurations: no timer, built-in dual-timer module, or NK-3 digital display with press buttons for precise interval control.

How it works

A special alloy-steel gear set draws oil from the reservoir and delivers it to the main line at 15 kgf/cm² rated, 25 kgf/cm² maximum, with volumetric efficiency of 75% or better. Self-absorbing performance is good enough that the pump can sit above the oil level.

The build decides the circuit. With the pressure take-off mechanism the pump cycles positive-displacement volumetric distributors, delivering a dosed volume to each point. Without it, the pump feeds resist-type distributors, delivering oil to each point in proportion.

A level switch is fitted as standard; a pressure switch is available. Fitted with both, the pump detects system pressure and oil level and integrates intermittence, operation and alarm functions automatically, on its own timer module or from the machine's PLC.

Control wiring: motor, timer module, level switch and pressure switch

How to read the order code

TZ-2232-410XTZ type lubrication pump · 100–200 cc/min discharge · 2P motor · NK-3 digital display microcomputer · single-phase 220 V · 4 L oil reservoir · 10 kgf/cm² pressure switch action · built-in pressure take-off mechanism.

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 · 3 = NK-3 dual-timer with digital display
Motor type: 1 = single-phase 100 V · 2 = single-phase 220 V · 3 = three-phase 200 V · 4 = three-phase 380 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: A = motor (blank = induction motor) · B = with buzzer · D = level switch up is on (blank = down is on)

Before you order

State voltage, reservoir size and take-off requirement on the order. None of the three is a field-change.
A pump ordered T (without take-off) will not cycle a volumetric distributor. Points will be starved with no visible fault.
Metal reservoirs are custom-made. Specify at time of order.
TZ-2211, TZ-3211, TZ-2231 and TZ-3231 (the 100 V single-phase timer and digital display codes) are made to order and not held in stock. MOQ and lead time are confirmed at quotation.

Warranty

One year against manufacturing defect from date of invoice.

How it pairs

The TZ Type Oil Lubrication Pump is commonly specified alongside the RH3 Type Volumetric Distributor, the 34 Type Volumetric Distributor, the 35 Type Volumetric Distributor, and the TCJ/TCZ Resist Type Distributor. That is the same recommendation carried on its own datasheet, not a generic same-category suggestion.

Industry applications

CNC Machining

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.

Injection Moulding

Tie bars, toggle pins and platens on horizontal and vertical machines: oil or semi-fluid grease, metered per point and re-metered every cycle.

Escalators & Conveyors

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.

35 Type volumetric distributorsRH3 Type inspecting volume distributorsTCJ / TCZ resist-type distributors
