A complete duplex vacuum station combining two oil-sealed single-stage rotary vane pumps, one 300 L vertical buffer receiver, two inlet filters, automatic isolation valves, a common suction manifold and PLC duty/standby control.
- Two-pump duty/standby availability
- 300 L buffer vessel for fluctuating demand
- PLC sequencing with independent pump isolation
مقدمة المنتج
The Central Vacuum Pump System consolidates multiple intermittent vacuum users onto one factory-assembled utility source. The selected purchasable configuration is a full-featured 300 L duplex station with two identical oil-sealed single-stage rotary vane pumps arranged around one vertical buffer receiver. Each pump branch includes its own inlet dust filter and electropneumatic isolation valve before joining the common suction manifold. A pressure sensor and analog gauge feed a side-mounted PLC cabinet that alternates the lead pump, starts the standby pump when demand rises and isolates a faulted branch. The receiver provides short-duration capacity and reduces excessive cycling. This industrial rough-vacuum package generates and buffers suction for clean manufacturing and laboratory utility loads; it is not a clean-steam, compressed-air, condensate-recovery or medical-gas source.
الخصائص الرئيسية
Master/spare sequencing shares operating hours and automatically calls the second pump when the vacuum setpoint cannot be maintained by the lead unit
One 300 L vertical receiver absorbs short demand peaks and gives the controller time to stage pumps without rapid motor cycling
A dedicated inlet dust filter on each pump branch protects the rotary vane mechanism from particles carried back from the distribution network
Individual electropneumatic isolation valves prevent an idle or faulted pump branch from becoming a leakage path into the common receiver
A common G2 suction connection simplifies connection to a central header serving multiple vacuum consumers
The local gauge, electronic pressure sensor and PLC cabinet keep vacuum status, setpoints, alarm logic and pump alternation in one serviceable package
Factory piping, wiring and a shared steel base reduce field assembly compared with separate pumps, a loose receiver and independently mounted controls
مخاوف المنتج للعملاء
A central vacuum station must be selected around simultaneous demand, pressure stability, inlet cleanliness, exhaust routing and the operating logic that makes redundancy useful.
Short peak loads can collapse header vacuum even when the average pump capacity appears adequateUse the 300 L receiver to buffer transient demand and size the two-pump staging thresholds from the measured simultaneous-load profile rather than the connected-device total alone.
A standby pump provides little resilience if an idle or failed branch leaks back through the common manifoldKeep one electropneumatic isolation valve on each pump branch, prove valve response during maintenance and configure the PLC to isolate a failed branch before calling the spare pump.
Dust, liquid carryover or aggressive vapour can shorten the life of an oil-sealed rotary vane pumpUse the two dedicated inlet dust filters for dry particles and add application-specific knock-out separation upstream when liquid carryover is possible; confirm gas compatibility before selection.
Frequent starts increase motor and contactor wear when the pressure band is too narrow for the receiver volumeSet separate start and stop thresholds, use delayed shutdown and equal-runtime sequencing, and review cycle counts after connecting the actual vacuum consumers.
Oil mist, heat and noise can migrate into occupied or controlled production areasInstall the station in a ventilated utility room, maintain the pump exhaust separators and route the common exhaust to a suitable discharge point without creating backpressure.
Undersized or leaking distribution piping can make the pump station appear too smallKeep the central header clean and leak-tight, use a bore appropriate for the design flow and distance, and verify pressure drop at the furthest simultaneous users before increasing pump capacity.

The locked catalogue identity is one full-featured CVS300-2XSV100B-class central station, represented without a third-party logo. It contains exactly one light-gray 300 L vertical carbon-steel buffer receiver with two dished ends, exactly two matching horizontal oil-sealed single-stage rotary vane pump assemblies at the base, exactly two blue electric motors, exactly two black cylindrical inlet dust filters, exactly two electropneumatic branch isolation valves, exactly one galvanized common suction manifold, exactly one round analog vacuum gauge, exactly one electronic pressure sensor, exactly one light-gray PLC control cabinet with one small HMI, one red emergency-stop button and one red/amber/green status beacon, exactly one black rectangular steel base with four leveling feet, one G2 common vacuum inlet, one G1 1/4 common exhaust connection and one G1/2 low-point drain. The selected reference duty is approximately 195 m³/h nominal combined pumping speed at 50 Hz, with pump-module ultimate pressure up to 0.5 mbar absolute under the stated catalogue conditions. Normal header setpoints are application-dependent and substantially higher than the pump's ultimate-pressure rating.
