{"product_id":"hc250-oil-free-piston-vacuum-pump","title":"HC250A\/B Oil-Free Piston Vacuum Pump","description":"\u003cp\u003eThe HC250 is a twin-cylinder oil-free piston vacuum pump for OEM equipment integration. The HC250A\/B series offers 220 V and 110 V versions, with single-stage and dual-stage vacuum configurations. The supplied datasheet lists power below 200 W, a 185 × 102 × 149 mm body and a net weight of 4.8 kg.\u003c\/p\u003e\n\u003ch2\u003eChoose the vacuum configuration for your process\u003c\/h2\u003e\n\u003cp\u003eThe single-stage configuration is listed with a flow rating of ≥75 L\/min and a maximum vacuum of -90 kPa. The dual-stage configuration is listed with ≥37.5 L\/min and a maximum vacuum of -98 kPa. These are separate flow and maximum-vacuum specifications, not a claim that the listed flow is maintained at maximum vacuum. Request a performance curve for your intended operating point before selecting a configuration.\u003c\/p\u003e\n\u003ch2\u003eCompact installation and electrical options\u003c\/h2\u003e\n\u003cp\u003eThe 123 × 70 mm mounting footprint supports installation planning in compact machines. Check clearance for hoses, wiring, cooling airflow and service access against the dimensional drawing. The datasheet lists 220 V \/ 110 V supply options and 1,400 \/ 1,700 rpm speeds; confirm the exact model, frequency and wiring with your quotation.\u003c\/p\u003e\n\u003cp\u003eClass F motor insulation, a four-pole motor and an automatic-reset thermal protector rated at 145 ± 5 °C are specified. The listed ambient range is -5 °C to +40 °C. Noise is listed as ≤50 dB(A); request the measurement conditions if noise performance is a selection criterion. Duty cycle and enclosure ventilation need application-specific confirmation.\u003c\/p\u003e\n\u003ch2\u003eApplications to discuss with your equipment team\u003c\/h2\u003e\n\u003cp\u003ePotential integration projects include laboratory filtration and sample handling, compact vacuum chambers, fixture holding and light automation. Selection depends on chamber volume, leakage, target pressure, process gases and cycle time. Oil-free describes the piston mechanism; it does not establish suitability for every gas, liquid, hazardous atmosphere or regulated medical use. Confirm material compatibility and any required inlet separation or filtration before use.\u003c\/p\u003e\n\u003ch2\u003eTechnical specifications\u003c\/h2\u003e\n\u003c!-- HCEM_SPEC_TABLE:HC250 supplied datasheet 2026-09-22 --\u003e\n\u003ctable class=\"hcem-spec-table\"\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth scope=\"col\"\u003eParameter\u003c\/th\u003e\n\u003cth scope=\"col\"\u003eHC250A\/B series\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003ePump design\u003c\/th\u003e\n\u003ctd\u003eTwin-cylinder oil-free piston vacuum pump\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eSupply options\u003c\/th\u003e\n\u003ctd\u003e220 V \/ 110 V; confirm frequency and model selection\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eRated power\u003c\/th\u003e\n\u003ctd\u003e\u0026lt;200 W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eSingle-stage configuration\u003c\/th\u003e\n\u003ctd\u003eListed flow ≥75 L\/min; maximum vacuum -90 kPa\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eDual-stage configuration\u003c\/th\u003e\n\u003ctd\u003eListed flow ≥37.5 L\/min; maximum vacuum -98 kPa\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eRated speed\u003c\/th\u003e\n\u003ctd\u003e1,400 \/ 1,700 rpm, depending on version\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eNoise\u003c\/th\u003e\n\u003ctd\u003e≤50 dB(A), datasheet value; test conditions on request\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eMotor\u003c\/th\u003e\n\u003ctd\u003e4 poles; Class F insulation\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eThermal protector\u003c\/th\u003e\n\u003ctd\u003eAutomatic reset, 145 ± 5 °C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eAmbient temperature\u003c\/th\u003e\n\u003ctd\u003e-5 °C to +40 °C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eDimensions (L × W × H)\u003c\/th\u003e\n\u003ctd\u003e185 × 102 × 149 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eMounting footprint\u003c\/th\u003e\n\u003ctd\u003e123 × 70 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eNet weight\u003c\/th\u003e\n\u003ctd\u003e4.8 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eThreaded connection\u003c\/th\u003e\n\u003ctd\u003e1\/4 inch; confirm thread standard and port assignment\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003ePower cable\u003c\/th\u003e\n\u003ctd\u003e650 ± 20 mm, black\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eGround cable\u003c\/th\u003e\n\u003ctd\u003e500 ± 20 mm, yellow-green\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003c!-- \/HCEM_SPEC_TABLE --\u003e\n\u003ch2\u003eQuestions before ordering\u003c\/h2\u003e\n\u003ch3\u003eWhich configuration should I select?\u003c\/h3\u003e\u003cp\u003eCompare the required operating vacuum and pumping speed, not just the maximum-vacuum number.
