Small Electromagnetic Lubrication Oil Pump — HTS Series (0.5 / 1 / 2 L)
The HTS electromagnetic lubrication oil pump uses an alternating solenoid to drive a piston, delivering way oil to CNC guides, spindles, and small machines with few lubrication points. It replaces larger electric gear pumps where compact size, quiet operation, and integrated timer control matter more than high continuous flow.
Typical ratings: max pressure ~1.0 MPa, discharge 1–99 ml/min adjustable (model dependent), reservoirs 0.5 L, 1 L, or 2 L, supply 110 V or 220 V AC (DC 24 V / 36 V on request per FAQ). Optional built-in digital timer and pressure gauge simplify cabinet mounting on lathes, mills, and transfer lines.
Outlet tubing is usually 4 mm or 6 mm nylon to SBJ metering units or restriction fittings in single-line oil layouts. For broader pump families see lube oil pump hub and larger reservoir oil pumps.
- Pressure: 0.5–1.0 MPa (model table)

Suffix B = with pressure gauge; D variants omit integrated timer (use external TC-2 controller if needed).
Built-In Digital Timer
Dual timers set lubricate duration and idle interval (10–999 minutes range on standard models). Independent of machine PLC on basic installs; can be interlocked with machine enable when wired per electrical drawing.
Inline Filter
Mesh filter on suction or outlet prevents chips and dust from reaching way ports and metering units. Inspect and clean at scheduled PM intervals; do not run without filter element installed.
Aluminum Casting Body
Die-cast aluminum housing keeps weight low for cabinet top mount and dissipates solenoid heat during frequent cycles. Powder-coated finish resists oil mist in machine enclosures.
Low-Noise Electromagnetic Motor
Alternating solenoid drive is quieter than gear pumps—suited for operator stations and light assembly lines where noise matters. Mount on rubber isolators if cabinet panels amplify vibration.
How Electromagnetic Oil Pumps Work
Each energize cycle of the solenoid advances a piston that pushes a fixed volume of oil into the supply line. When the coil de-energizes, the piston returns and refills from the reservoir. Rapid cycling produces continuous micro-flow suitable for way lubrication where steady oil film matters more than high peak flow.
Typical CNC Installation
- Mount pump tank above or beside machine cabinet; fill with clean way oil.
- Connect 4 or 6 mm outlet to distributor or direct to meter units.
- Set lubricate time and pause time on built-in timer (or external controller).
- Adjust flow screw for 1–99 ml/min range per model HTS05-8.
- Run manual shot; verify oil at each way port before production.
When to Choose HTS vs Other Oil Pumps
| Need | HTS electromagnetic | Alternative |
|---|---|---|
| Few points, compact CNC cabinet | HTS 0.5–2 L | — |
| Higher continuous flow, 4–6 L tank | — | 4 kg oil pump |
| Hand backup / service | — | Hand oil pump |
| Mobile 12/24 V | — | Timer + DC pump skid |
Maintenance
- Keep reservoir above minimum mark; low oil causes air lock and noisy solenoid.
- Clean suction strainer and inline filter mesh periodically (see Section 2).
- Replace seals if output drops at same flow setting.
- Use only recommended viscosity; thick oil slows piston return in cold shops.

Standard HTS models are offered in 110 V and 220 V AC. DC 24 V and 36 V variants are available on request for battery or control-voltage cabinets—specify when ordering.
Rated maximum is 1.0 MPa on listed HTS models. Set relief and line components for this class; do not exceed meter unit or fitting ratings downstream.
0.5 L (HTS05), 1 L (HTS01), and 2 L (HTS02). Choose tank size from daily oil consumption and refill access—2 L suits longer unattended shifts.
Typically 4 mm for final legs and 6 mm for main branches to the distributor. Match push-in or compression fittings to tube OD.
ISO VG 32–68 cSt way and spindle oils at operating temperature. Heavier oils may require longer pause times or a higher-flow pump model.
Models with -8B suffix include a gauge; -8 without B omits gauge. D suffix models omit integrated timer—pair with external controller if required.
Yes, when point count is low and total flow fits HTS output. Verify electrical supply, tank capacity, and that meter units match the new pump cycle timing.
