Lowara DIWA 230V Submersible Pumps

Free Delivery2 Year GuaranteeBest Price GuaranteeFree Expert Advice

Lowara DIWA pumps are high quality, corrosion resistant submersible pumps - Ideal for draining cellars, garages, construction sites, emptying tanks and reservoirs, lawn and garden irrigation and pumping domestic wastewater (washing machines, showers, sinks etc...).  
GT versions have compact tubular float switch, allowing the DIWA pump to be used where standard float design can-not work due to insufficient space.

To ensure long life, the pumps motor has a built in thermal overload protection and a double mechanical seal system in wear resistant silicon carbide to prevent water ingress. The stainless steel rotating shaft is also protected by a lip seal and V-Ring which prevents sand and other abrasive material damaging the shaft seals. The seal system is continuously lubricated by Lowara’s DRIVELUB system ensuring long life, trouble free operation. The motor is cooled by the pumped liquid, which means that the pump can run partially submerged without damage.

DIWA pumps have a special polyurethane internal coating for maximum resistance to abrasion.
