Product Overview
Featuring a top-pull-out structural design, the TP 50-190/4 inline pump allows service access to the electric motor and bronze impeller assembly without disconnecting the pump body from connected piping. The pump handles clean water fluid circulation across commercial HVAC distribution loops under continuous operation.
The hydraulic wet-end achieves a rated flow capacity of 439 L/Min with a maximum head rating of 19 m. Cast iron housing materials provide solid pressure containment up to 16 bar. The internal assembly houses a bronze impeller fitted with bronze wear rings. Net equipment weight is 81.6 kg.
Power specifications call for a 415 V three-phase electrical supply rated at 2.2 kW motor power. Current draw under load measures 4.4 Amps. Operating fluid temperatures span -25°C to 120°C with a maximum working pressure rating of 16 bar. The housing features opposite DN 50 flanged ports for mounting.
The electric motor carries an IP55 ingress protection rating alongside Class F thermal insulation and integrated PTC thermistors. System maintenance relies on top-pull-out architecture, enabling drive head disassembly while the pump casing stays secured to pipe runs.
Features
- 2.2 kW motor driving a bronze impeller to produce 439 L/Min at 19 m head.
- EN-GJL-250 cast iron volute with cataphoresis electrocoating for hydronic loop service.
- Opposite DN 50 flanged ports enabling direct insertion into commercial pipework runs.
- 4.4 Amps rated current draw at 415 V three-phase supply voltage.
- BQQE mechanical shaft seal with bronze wear rings for clean water circulation duty.
- IP55 motor enclosure rated for dust and water spray protection in plant room environments.
- Top-pull-out structural design permitting service access without disturbing pipework connections.

What motor kilowatt rating, incoming voltage feed, and operational amperage apply to this unit?
The four-pole motor powering Grundfos TP 50-190/4 consumes 2.2 kW across a three-phase 415 V electrical connection, drawing 4.4 Amps.
Under low-speed four-pole circulation, what fluid operating range and pressure limits govern it?
Thermal capabilities engineered into TP 50-190/4 permit media temperatures across -25°C to 120°C under line pressures up to 16 bar.
Operating with reduced rotational acoustic levels, what elevation rating applies to this pump?
Reduced rotational velocity allows TP-50-190-4 to sustain a quiet dynamic head of approximately 19 m.
Moving fluid with minimal line turbulence, what maximum volumetric capacity is certified?
Moving tempered water with minimal line turbulence, TP 50 190 4 achieves a flow capacity of approximately 439 L/Min.
To prevent electrochemical oxidation, what surface protection is applied to this cast housing?
The four-pole wet end assembly of TP/50/190/4 pairs an EN-GJL-250 cast iron housing with a precision-cast bronze impeller.
