Davey DC10A and DC10M pumps handle clean-water sump emptying, water transfer and emergency flood relief, with a maximum flow of 80L/min and maximum total head of 6m. Actual flow depends on lift and pipe resistance; refer to the performance curve to assess expected flow. They also suit domestic fountains and waterfalls that are not used for fish or aquaculture. The DC10A has a preset-length float switch for automatic water-level control. The DC10M is supplied without a float switch and needs manual switching or a separately installed level controller. Performance is 40L/min at approximately 3.5m head.
Both models have a 25mm (1") BSP male thread outlet and can pump neutral-pH clean water containing up to 10% small soft organic solids below 4mm diameter. They are not intended for sewage, abrasive sand or grit, fishponds or aquaculture.
The 100W motor operates on 220-240V single-phase, 50Hz power and has automatic-reset thermal overload protection. Both models have a 10m oil-resistant lead with a 3-pin plug.
For a 10m lead, use a maximum installation submergence of 7m. Position the pump upright on a firm base, clear of silt, and use a rope attached to the handle for lifting. Allow the DC10A float to move freely. Switch the DC10M off when the water level falls to the top of the pump housing, unless a suitable external level controller performs this function.
The double casing directs pumped water around the motor shell before it leaves the outlet, providing cooling when the pump is only partially submerged. This makes the pumps useful in shallow pits where the water level falls below the top of the motor during pumping. The pump must still have water available at the inlet and must not run dry.
An ABS outer casing, strainer and handle surround a 304 stainless steel motor shell. The pump casing is glass-filled ABS and the impeller is polycarbonate. A silicon carbide/ceramic mechanical shaft seal operates in a captive oil bath, with an oil seal and sand-slinger lip seal providing additional protection.
The DC10A and DC10M carry a two-year Davey warranty, subject to the manufacturer conditions.

Grundfos SP 1A pumps supply clean groundwater for domestic water systems, irrigation and pressure boosting. Rated flow is 1m3/h (16.7L/min), with rated heads from 35m to 199m across these models. Each head rating is stated at that same rated flow; actual flow depends on pumping lift, required outlet pressure and pipe resistance. Use the matching 50Hz curve to assess expected flow for the installation.
The outlet is 32mm (1 1/4") Rp / BSP female thread. These pumps handle clean, thin, non-aggressive water with a maximum sand content of 50g/m3. They are not sewage or solids-handling drainage pumps. A built-in non-return valve reduces return flow when the pump stops.
The 240V single-phase three-wire versions include a starter. The 240V single-phase two-wire version has its starting device built into the motor. Both single-phase types have thermal protection that cuts power if the motor overheats. The 415V three-phase versions require a motor-protection device that cuts power if the motor overloads, with its settings matched to the motor nameplate.
For automatic operation, connect suitable tank-level or pressure controls. Where the water level could fall below the pump inlet, use dry-running protection to stop the pump before it draws in air. Extend the motor lead with correctly sized submersible cable and a suitable waterproof cable joint for the installation depth.
Keep the pump inlet submerged below the lowest water level reached while pumping. At least 0.5m of water above the inlet is recommended; greater submergence may be needed to maintain adequate pressure at the inlet. Maximum installation depth is 150m below the water surface. Install vertically with the motor below the pump and support the assembly with suitable pipework and installation hardware. Do not lift or suspend it by its electrical cable.
Liquid temperature is +2 to +40°C. Water must pass around the outside of the motor at a speed of at least 0.15m/s (15cm/s) to cool it. In a wider bore, the same pump flow moves more slowly around the motor. Fit a cooling sleeve if the installation cannot provide the required speed; the sleeve directs water past the motor. SP 1A pumps are suitable for continuous operation without scheduled cooling stops, provided the inlet stays submerged and the specified flow, motor cooling and liquid temperature limits are maintained.
The pump and impellers are AISI 304 stainless steel. Multiple impeller stages build head through the pump, while water-lubricated bearings support the rotating assembly. The Grundfos MS402 submersible motor is rated IP68 with Class B insulation.

240V single phase, three wire: external starter included. The 0.55kW and 0.75kW MS402 versions have built-in thermal protection. The 1.1kW MS402 also requires external current protection. The 1.5kW MS402 and 2.2kW MS4000 versions require external motor protection in a suitable starter/control box or separately. The 3.7kW ULTRA PSC versions use a CSCR starter for the required starting torque.
415V three phase: External motor protection is required to cut power if the motor overloads. Match protection settings to the current shown on the motor nameplate. Use a suitable motor-protective circuit breaker or a motor-protection unit with an electrically operated switch.
For automatic operation, connect suitable tank-level or pressure controls. Where the water level could fall below the pump inlet, use dry-running protection to stop the pump before it draws in air. Extend the motor lead with correctly sized submersible cable and a suitable waterproof cable joint for the installation depth.
Keep the pump inlet submerged below the lowest water level reached while pumping. At least 0.5m of water above the inlet is recommended; greater submergence may be needed to maintain adequate pressure at the inlet. Maximum installation depth below the water surface is 150m for MS402 and ULTRA versions, and 600m for MS4000 versions. The SP 7-17 single-phase set uses MS4000; its three-phase counterpart uses MS402. Install vertically with the motor below the pump and support the assembly with suitable pipework and installation hardware. Do not lift or suspend it by its electrical cable.
Liquid temperature is +2 to +40°C. Water must pass around the outside of the motor at a speed of at least 0.15m/s (15cm/s) to cool it. In a wider bore, the same pump flow moves more slowly around the motor. Fit a cooling sleeve if the installation cannot provide the required speed; the sleeve directs water past the motor.
The MS402 and MS4000 versions can run continuously without scheduled cooling stops while the inlet stays submerged and the specified flow, motor cooling and liquid temperature limits are maintained.
The pump and impellers are AISI 304 stainless steel. Multiple impeller stages build head through the pump, while water-lubricated bearings support the rotating assembly.
Grundfos motor versions have a two-year limited manufacturer warranty. The Australian catalogue specifies a one-year motor warranty for ULTRA motors. Warranty terms and applicable consumer rights apply.

Franklin Bore Pump Installation & Operation
Franklin 4-inch Motor Installation & Operation
Franklin Motor Technical Guide (Australia & NZ)
Franklin FPS 9A High Capacity multistage bore pumps supply water for irrigation, tank filling and domestic or commercial water systems. At 140L/min, these models deliver 23-146m head, depending on model. These figures exclude check-valve losses. Packages combine a High Capacity pump with a Franklin 4-inch motor.
The performance figures describe the pump end without check-valve losses. Actual delivery depends on pumping lift, required outlet pressure, check-valve losses and pipe resistance. Use the 50Hz performance chart to assess expected flow for the installation. The pump operating range is approximately 50-190L/min, with best efficiency at approximately 90-170L/min.
The outlet is 50mm (2") BSP female thread. An integrated stainless-steel wafer-style non-return valve reduces return flow when the pump stops. These pumps are for bore water with minimal sand or sediment.
230V single phase, two wire. The BIAC starting switch is built into the motor. Motor overload protection stops the motor if it overheats or overloads. Two supply conductors plus protective earth.
230V single phase, three wire. Matching capacitor starter/control box included. The motor has built-in overload protection. Three motor conductors plus protective earth.
400V three phase. Requires a motor starter and motor-overload protection matched to the supplied motor nameplate. This protection cuts power if the motor overloads.
For automatic operation, connect suitable tank-level or pressure controls. Where the bore water level could fall below the pump, use dry-running protection to stop it before it draws in air. Extend the motor lead with correctly sized submersible cable and a waterproof joint for the installation depth.
Install vertically with the motor below the pump, allowing clearance for the pump, cable and pipe connections. Maximum motor submergence is 150m below the water surface. Keep the assembly at least 1.5m above the bore bottom and position it so water passes the motor before entering the pump. Support it with suitable pipework and a safety cable; never lift or suspend it by the electrical cable.
