Grundfos UNILIFT AP35B.50.06.A1V handles dirty stormwater, groundwater and suitable non-aggressive wastewater, with a maximum flow of 300L/min and maximum head of 11m. These are separate limits. Actual flow depends on lift and pipe resistance; use the matching 50Hz curve to assess expected flow. Performance is 100L/min at approximately 7.4m head.
The horizontal side outlet is 50mm (2") Rp / BSP female thread. Maximum spherical particle diameter is 35mm. Suitable for water containing small amounts of suspended solids, but not stones, long fibres, aggressive or flammable liquids.
Suitable uses include collecting pits, dirty stormwater, groundwater lowering, suitable laundry and bathroom wastewater, and suitable septic-system effluent. This model excludes sewage and toilet discharge.
The supplied tethered float starts and stops the pump automatically. Adjust its free cable length to set the difference between start and stop levels, and maintain free float movement.
For continuous running without scheduled cooling rests, keep the motor and inlet completely submerged. For intermittent pumping with cooling rests, keep at least half the motor submerged and follow the manual limit of maximum 5 minutes running per 30 minutes when the motor is not fully submerged. Do not run dry.
Install on a firm base clear of sludge and mud. An auto-coupling installation is optional; coupling equipment is not supplied. Allow a minimum pit diameter of 550mm and depth of 600mm at the minimum free float-cable setting. Maximum installation depth is 7m with the 10m cable; leave at least 3m of cable above liquid level. Lift by the handle. A union, non-return valve and isolating valve are recommended for permanent pipework.
Supply is 220-240V single phase, 50Hz. Input P1 is 1kW and motor output P2 is 0.66kW. A 10m cable and Australian plug are supplied. Internal thermal overload protection resets after cooling; no separate motor-protection control box is needed.
The housing and vortex impeller are AISI 304 stainless steel. Liquid temperature is 0-40°C and pH is 4-10. A composite ring stand supports the pump, and housing clips provide access for cleaning.
Two-year manufacturer warranty, subject to Grundfos warranty terms and applicable consumer rights.
