HARPIA 1100 S – positive displacement wastewater pump with grinder
The IPRO HARPIA 1100 S positive displacement pump is a high-pressure unit with a grinder, designed for pumping domestic wastewater. WUnlike typical centrifugal pumps, its positive displacement design enables it to achieve high discharge pressure even with a low-power motor, making it possible to pump wastewater to great heights through narrow pipelines.
Who it's for
-
Property owners with a large elevation difference to overcome when pumping – high discharge pressure of up to 110 m allows wastewater to be pumped to great heights through narrow pipelines.
-
Companies installing domestic wastewater pumping stations – the disc grinder shreds solid waste and fecal matter, making it easier to pump wastewater through small-diameter pipelines.
-
Households without the option of gravity-fed wastewater drainage – the pump is suitable for use in a tank with the liquid level controlled by a control plug or float switch.
-
Service technicians and installers – the modular design and availability of spare parts (including the cutting ring and mechanical seal) make maintenance and repairs easier.
Applications
The HARPIA 1100 S positive displacement pump is designed for pumping domestic wastewater. A disc grinder integrated with the shaft, known as a cutting ring, shreds solid waste and fecal matter at the pump inlet, while a steel spiral screw rotor working with a rubber stator pumps the shredded liquid through small-diameter pipelines. Wastewater is pumped until the liquid level in the tank drops to the cutoff level, using a control plug or float switch.
The HARPIA 1100 S positive displacement pump is well suited to situations where wastewater must be pumped to a great height using a low-power motor, for example from a domestic pumping station to a collector located above the level of the installation.
HARPIA 1100 S features – description and technical specifications
The motor and pump housings are made of gray cast iron, while the base and handle are made of stainless steel, providing corrosion resistance in constant contact with wastewater. The 410 stainless steel screw rotor works with a flexible NBR stator whose curves are matched to the rotor shape, delivering high discharge pressure with low power consumption. The hardened 440 stainless steel cutting ring grinds solid contaminants and fecal matter at the pump inlet, allowing them to be safely pumped through a pipeline with a diameter of just DN32.
The motor is insulated to Class F and features automatic thermal overload protection, which switches off the pump if it overheats due to low voltage, contaminants, or other operating faults. After about 10 minutes, the motor cools down and restarts automatically. The double SiC/SiC mechanical seal protects the motor chamber from liquid ingress, even during prolonged submerged operation.

Frequently Asked Questions (FAQ) – HARPIA 1100 positive displacement pump S
What is the HARPIA 1100 S pump designed for?
The IPRO HARPIA 1100 S positive displacement pump is designed for pumping domestic wastewater. Its integrated disc grinder grinds solid contaminants and fecal matter, allowing the liquid to be safely pumped through a small-diameter pipeline.
What is the difference between the S version and the T version?
The S version is single-phase, powered at 1~230 V, and draws 10.5 A, while the T version is three-phase, powered at 3~400 V, and draws 3.5 A. Both versions have identical hydraulics, a motor power of 1.1 kW, and operating parameters.
How deep can the HARPIA 1100 S pump be submerged?
The maximum pump submersion depth is 7 m. The pump can operate continuously provided it is fully submerged in the pumped liquid.
How is the pump protected against motor overheating?
The pump is equipped with automatic thermal overload protection, which shuts off the motor if it overheats due to low voltage, contaminants in the pump, or other faults. The motor cools down in about 10 minutes and restarts automatically.
What types of wastewater should the HARPIA 1100 S pump not be used with?
Due to the cast-iron construction of most of the pump’s components, it should not be used with highly corrosive media or media containing highly corrosive or abrasive solid particles.
Where can you buy the HARPIA 1100 S positive displacement pump?
Dambat does not sell directly. The HARPIA 1100 S pump is available from trade partners, plumbing wholesalers, and authorized online distributors.
What warranty terms apply to the HARPIA 1100 S pump?
IPRO – 36 months (3 years) manufacturer’s warranty. Dambat provides warranty and post-warranty service.
