The V-135 Diaphragm Vacuum Pump is the highest-capacity model in the V Series — delivering 125 L/min maximum flow for industrial vacuum systems, large-scale laboratory operations, and continuous chemical processing applications that exceed the flow capacity of compact and mid-range diaphragm vacuum pumps. The V-135 introduces two capabilities unique in the V Series: vacuum adjustment for real-time control of the operating vacuum level, and a real-time display showing current vacuum status — enabling operators to monitor and modify the vacuum conditions of connected processes during operation without external vacuum gauges or manual adjustment. At 600W with PTFE pump head, PTFE composite diaphragm, FPM valves, and continuous operation rating — the V-135 provides industrial-scale clean, oil-free, chemically resistant vacuum for the most demanding laboratory and process environments.

The V-135 Diaphragm Vacuum Pump leads the V Series in capacity and control — delivering 125 L/min of oil-free PTFE vacuum at 8 mbar with real-time vacuum adjustment display, two-stage PTFE pump head, FPM valves, direct drive, and continuous duty rating for industrial vacuum systems, large-scale laboratory operations, and continuous chemical processing applications.
The V-135's 125 L/min maximum flow — nearly double the V-65's 65 L/min and over six times the V-20's 20 L/min — provides the vacuum throughput required for industrial-scale vacuum systems where fast evacuation of large chamber volumes, high-rate vapour condensation support, and multi-application simultaneous supply define the operational requirements. At 125 L/min, the V-135 supports the vacuum system flow demands of large rotary evaporator installations, industrial-scale vacuum filtration systems, and multi-instrument vacuum supply networks in large chemical and pharmaceutical production-adjacent laboratories.
The V-135's PTFE pump head and PTFE composite diaphragm process the largest volume of corrosive chemical vapour per unit time in the V Series — making the PTFE's chemical inertness the most critical performance specification for maintaining consistent service life in industrial-scale continuous corrosive gas environments. At 125 L/min continuous flow in a demanding chemical or pharmaceutical production environment, the difference between PTFE and standard polymer or rubber materials for the pump head and diaphragm is measured in service months and years of additional reliable operation before component replacement is required.
The V-135's oil-free design provides industrial-scale clean vacuum without the oil management complexity of equivalent-flow oil-sealed rotary vane pumps — which at 125 L/min equivalent flow would require large oil reservoirs, frequent oil changes, oil mist traps, and oil disposal management that represent significant operational overhead in continuous industrial production environments. The V-135's maintenance-free oil-free operation reduces the total maintenance burden of the vacuum system while providing cleaner vacuum output appropriate for pharmaceutical and food-adjacent process applications.
The V-135 is designed and specified for continuous industrial operation — with motor, pump head, diaphragm, valve, and structural components specified for sustained high-flow continuous duty cycles at 600W. In industrial chemical processing and large-scale laboratory applications where vacuum must be maintained without interruption for extended production periods, the V-135's continuous working system specification ensures reliable performance throughout the full production or analytical campaign duration.
The V-135 uniquely offers vacuum adjustment capability with a real-time display of current vacuum level — enabling operators to set and monitor the operating vacuum during active processes directly from the pump. This capability is particularly valuable in process applications where different steps require different vacuum levels — such as rotary evaporation protocols where vacuum is progressively reduced to maintain constant evaporation rate as solvent composition changes, or industrial drying applications where vacuum level is adjusted based on moisture content monitoring. The real-time display eliminates the need for separate external vacuum gauges for process monitoring.
Despite its 125 L/min flow capacity and 600W power, the V-135 maintains a compact exterior at 380 × 300 × 200 mm — remarkably space-efficient for an industrial-flow pump. This compact footprint makes the V-135 practical for bench or cart mounting in laboratory installations where floor space is at a premium, while still providing the industrial vacuum capacity required for large-scale operations. The compact design reflects the efficiency advantages of the direct drive diaphragm mechanism over alternative high-flow vacuum pump technologies at equivalent flow rates.
The V-135 Diaphragm Vacuum Pump incorporates three safety systems — overheat protection, stable vacuum control, and reliable motor and system protection — providing safe continuous operation for industrial vacuum systems, large-scale laboratory applications, and continuous chemical processing environments.
The V-135's overheat protection system monitors the 600W motor temperature and activates automatic shutdown if the limit is exceeded — the most critical safety feature for the highest-power model in the V Series operating under sustained high-flow industrial duty. At 600W continuous operation, thermal management is the primary reliability challenge — adequate ventilation clearance (minimum 200 mm on all sides) and installation away from heat sources are essential prerequisites for reliable overheat protection avoidance in the V-135's industrial and large laboratory use contexts.
The V-135's vacuum adjustment and real-time display system provides stable, controllable vacuum throughout connected industrial processes — preventing uncontrolled vacuum level fluctuations that could affect product quality in pharmaceutical drying applications or cause safety events in high-vapour-pressure chemical processes where precise vacuum control prevents uncontrolled boiling or evaporation. The stable vacuum control combines the V-135's consistent two-stage pumping performance with the operator's ability to actively manage vacuum level through the adjustment interface.
The V-135's 600W motor and associated electrical systems incorporate protection appropriate for the highest-power model in the V Series — with motor winding insulation, electrical connection ratings, and thermal management specified for industrial continuous duty at the V-135's rated 600W power level. Reliable system protection ensures operational continuity in industrial environments where vacuum pump failure would have significant process interruption consequences.
