SWQ 1300 230 V submersible grinder pump with float
The SWQ 1300 is a 1.3 kW submersible steel pump with an open cutting system, designed for pumping wastewater and dirty water containing organic matter. The SWQ grinder series is designed for use in septic tanks, pumping stations, and domestic treatment plants – the dual-channel gray cast iron impeller with a cutting assembly shreds organic matter before it reaches the hydraulics, eliminating the risk of system blockage.
Who it's for
-
Water and sewer network installers – the 2" threaded connection and built-in float allow the pumping station to be started quickly without additional automation.
-
Owners of septic tanks and domestic treatment plants – the grinder eliminates the need to pre-filter tank contents, and the pump handles typical septic tank contents without the risk of clogging.
-
Farms – a capacity of 417 l/min makes it possible to efficiently empty large settling tanks and moderately thick slurry tanks.
-
Maintenance departments – dual protection (thermal protector in the winding + overcurrent circuit breaker on the cable) protects the motor if the cutting system becomes blocked and allows operation without constant supervision.
Applications
The SWQ 1300 is designed for pumping domestic wastewater, dirty water from septic tanks and settling tanks, and supplying domestic biological treatment plants. The open cutting system made of gray cast iron shreds soft organic matter – food scraps, paper, fibers – before it reaches the impeller. The pump is not suitable for media containing sand, gravel, or other mineral contaminants, which abrade the Ceramic/Graphite/NBR seal and cutting system.
The built-in float automatically switches off the pump when the liquid level drops, protecting the motor from running dry. An additional overcurrent circuit breaker on the power cable cuts off the power if the cutting system becomes mechanically blocked – this is a separate protection system, independent of the thermal protector, which responds to a sudden increase in power consumption before the winding is damaged.

Frequently asked questions (FAQ) – SWQ 1300 submersible pump with grinder
What does the grinder actually do – is it the same as a septic tank pump?
The grinder is an open cutting system mounted at the pump inlet – it grinds soft organic matter (paper, food scraps, fibers) before it reaches the impeller. This allows the pump to push septic tank contents through a smaller-diameter pipe without the risk of clogging. It’s not the same as a clean-water pump – the SWQ 1300 is specifically designed for this type of liquid.
How does the SWQ 1300 differ from the SWQ 2200 with a grinder?
Both models have identical cutting system designs and use the same materials. The difference is power and performance: the SWQ 1300 (1.3 kW, 417 l/min, 10 m head) is suitable for typical septic tanks and residential pumping stations. The SWQ 2200 (2.2 kW, 333 l/min, 18 m head) is the right choice when greater head is needed – for a longer discharge pipe or a higher outlet.
What happens if a stone or piece of metal gets into the pump?
The cutting system and gray cast iron impeller are not designed for hard solids – stones or metal can damage or block the impeller. The cable-mounted overcurrent switch responds to a sudden increase in power draw and cuts off the power before the motor burns out. Once the obstruction is removed, the pump can be restarted, but it’s worth checking the condition of the cutting system.
What damages this pump the fastest?
Sand and fine mineral particles in the liquid wear down the cutting system and ceramic seal much faster than normal use. Another risk is dry running when the float switch is blocked. A third is that regularly pumping liquids with a high fat content can cause deposits to build up on the cutting system and gradually reduce performance.
Where can I buy the SWQ 1300 pump?
The pump is available from Dambat’s sales partners, specialist plumbing wholesalers, and authorized online distributors. Dambat does not sell directly.
Where can I get it serviced after the warranty expires?
Warranty and post-warranty service is provided by Dambat, Adamów 50, Grodzisk Mazowiecki. IBO – 24-month (2-year) manufacturer’s warranty.
