Model code decoder

Paste the model code from a pump's nameplate and read what it says: capacity, motor, timer, reservoir and options. It reads the ordering scheme published in each factory manual, for the TZ, HL, GM and ZJ pumps.

TZ type oil lubrication pump

How a TZ code is read

From the ordering guide in the factory manual (PDF). See the TZ Type Oil Lubrication Pump for the specification.

What each position of a TZ model code means
Position	What the code says
Discharge capacity	`2` 110 ml/min at 50 Hz (130 at 60 Hz) `3` 220 ml/min at 50 Hz (260 at 60 Hz) The guide gives no figures for this position. These come from the specification table in the same manual.
Motor poles	`2` 2-pole motor
Timer module	`0` No timer module `1` Built-in microcomputer timer (free setting of action and interval) `3` NK-3 timer with digital display and buttons The guide's own list says 'without' against both 0 and 1. The manual's model notes say TZ-2211, 2212, 3211 and 3212 carry the built-in microcomputer, so 1 is read as fitted.
Motor supply	`1` Single phase 100 V `2` Single phase 220 V `3` Three phase 200 V `4` Three phase 380 V
Reservoir	`2` 2 L `4` 4 L
Pressure switch	`10` Switch acts at 10 kgf/cm² `05` Switch acts at 5 kgf/cm² `00` No pressure switch
Pressure take-off	`X` Built-in pressure take-off (for volumetric distributors) `T` No pressure take-off (for resist-type distributors)
Motor option	`A` Motor option A (the factory guide gives no further detail) No letter: induction motor
Buzzer	`B` With buzzer (TZ-2202 series) No letter: no buzzer
Level switch	`D` Level switch: up is on No letter: level switch: down is on

Worked example from the guide. TZ-2232-410X is read as 2 2 3 2 4 10 X: A TZ pump with a single phase 220 V motor and the NK-3 digital timer, a 4 L reservoir, a pressure switch acting at 10 kgf/cm² and a built-in pressure take-off.

HL type oil lubrication pump

How a HL code is read

From the ordering guide in the factory manual (PDF). See the HL Type Oil Lubrication Pump for the specification.

What each position of a HL model code means
Position	What the code says
Discharge capacity	`1` 0 to 100 cc/min `2` 100 to 200 cc/min `3` 200 to 300 cc/min
Motor poles	`2` 2-pole motor
Timer module	`0` No timer module `1` Built-in dual-timer module The guide's own list says 'without' against both 0 and 1. Its worked example, HL-2212-210X, reads 1 as 'with built-in dual-timer module', so 1 is read as fitted.
Motor supply	`1` Single phase 100 V `2` Single phase 220 V
Reservoir	`2` 2 L `4` 4 L
Pressure switch	`10` Switch acts at 10 kgf/cm² `05` Switch acts at 5 kgf/cm² `00` No pressure switch
Pressure take-off	`X` Built-in pressure take-off `T` No pressure take-off
Level switch	`D` Level switch: up is on No letter: level switch: down is on

Worked example from the guide. HL-2212-210X is read as 2 2 1 2 2 10 X: An HL pump delivering 100 to 200 cc/min, with a single phase 220 V motor and built-in dual-timer module, a 2 L reservoir, a pressure switch acting at 10 kgf/cm² and a built-in pressure take-off.

GM type grease lubrication pump

How a GM code is read

From the ordering guide in the factory manual (PDF). See the GM Type Grease Lubrication Pump for the specification.

What each position of a GM model code means
Position	What the code says
Discharge capacity	`2` 100 to 200 cc/min `3` 200 to 300 cc/min `4` 300 to 400 cc/min
Motor poles	`2` 2-pole motor
Timer module	`0` No timer module `1` Built-in dual-timer module `3` NK-3 timer with digital display and buttons (4 L pump only)
Motor supply	`1` Single phase 100 V `2` Single phase 220 V `3` Three phase 200 V `4` Three phase 380 V
Reservoir	`2` 2 L `4` 4 L
Pressure switch	`30` Switch acts at 30 kgf/cm² `00` No pressure switch
Pressure take-off	`X` Built-in pressure take-off (for use with a dosing distributor) `T` No pressure take-off (for use with a resist-type distributor)
Level sensor	`S` With capacitance-type level sensor No letter: no level sensor

Worked example from the guide. GM-3204-230X is read as 3 2 0 4 2 30 X: A GM grease pump delivering 200 to 300 cc/min, with no timer module and a three phase 380 V motor, a 2 L reservoir, a pressure switch acting at 30 kgf/cm² and a built-in pressure take-off.

ZJ type high-pressure grease pump

How a ZJ code is read

From the ordering guide in the factory manual (PDF). See the ZJ Type High Pressure Grease Pump for the specification.

What each position of a ZJ model code means
Position	What the code says
Discharge capacity	`3` 2 to 3 mL/min (single pumping unit) `6` 4 to 6 mL/min (double pumping unit)
Motor	`5` DC 12 V `6` DC 24 V
Controller	`0` No controller `1` Time-programming controller `2` Time-travel controller
Reservoir	`2` 2 L (1.9 kg) `3` 2.5 L `4` 4 L (4 kg) `8` 8 L (8 kg)
Chassis	`P` High-strength plastic chassis No letter: aluminium alloy chassis
Level switch	`S` With level switch No letter: no level switch
Output	`V` Adjustable output No letter: fixed output stroke

Worked example from the guide. ZJ3612S is read as 3 6 1 2 S: A ZJ grease pump delivering 2 to 3 mL/min from a single pumping unit, with a DC 24 V motor, a time-programming controller, a 2 L reservoir, an aluminium alloy chassis, a level switch and a fixed output stroke.

What this does not cover

When a code will not decode

Everything above comes from the ordering guide in each factory manual, and only from there. The India range also includes variants those guides do not list: the TZ pump, for instance, is supplied here for 24 V DC, 110 V AC and 415 V three-phase, none of which has a code in the guide. A code outside the scheme is shown as such rather than guessed at.

The 34, 35 and RH-3 distributors give their outlet capacities digit by digit in a code of variable length, and the guides for the other pumps either publish no scheme or one we have not encoded yet. For any of those, or a code that stops decoding partway, send us the nameplate.
