Grundfos TP 40-160/2 A F A BQQE FX2 415V Circulator Pump 99412627 DN40 0.75kW #4489

GRUNDFOS TP 40-160/2 A-F-A-BQQE FX2 – 0.75 kW 415V In-Line Circulator Pump (99412627) #4489

This listing is for a Grundfos TP pump from the TP family of dry-rotor, single-stage in-line circulator pumps. It is a single-head, fixed-speed unit with identical in-line suction and discharge ports, designed for heating, cooling and industrial circulation duties where robust, serviceable pump construction is required.

The pump uses the top-pull-out design, meaning the power head (motor, pump head and impeller) can be removed for maintenance while the pump housing remains in the pipework.

Frequency note:
The manufacturer performance data for this model is published based on 60 Hz. The motor can be operated on 50 Hz or 60 Hz; when used on 50 Hz the hydraulic performance (flow and head) will be proportionally lower than the 60 Hz curves.

Condition: supplied as pictured. The unit is inspected prior to dispatch.
Guarantee: supplied with our 2-year guarantee.

Frequently Asked Questions

What does the model number mean?

• TP – TP pump range (dry-rotor in-line circulator)
• 40 – nominal diameter of inlet and outlet ports (DN40)
• 160 – head series designation
• /2 – 2-pole motor
• A – basic version
• F – DIN flange connections
• A – basic version
• BQQE – shaft seal code
• FX2 – F: 0.75 kW power code, X: USDOE regulated motor, 2: 2-pole, 60 Hz design

What does the BQQE shaft seal code mean?

• B – rubber bellows seal construction
• Q – silicon carbide seal face
• Q – silicon carbide counterface
• E – EPDM elastomers

Seal operating temperature (BQQE): suitable from –25 °C up to 120 °C in water duties (EPDM-limited).

Why choose the BQQE seal?

BQQE uses a silicon-carbide against silicon-carbide face pairing. This provides excellent wear resistance and strong performance in hot-water circulation duties, particularly where long running hours and resistance to fine abrasive particles are priorities.

Can this pump run on 50 Hz as well as 60 Hz?

Yes. The motor is designed to operate on both 50 Hz and 60 Hz supplies. The published curves are based on 60 Hz; when operated on 50 Hz the pump will run at a lower speed and the resulting flow and head will be proportionally reduced.

Is this suitable to replace other DN40 circulators?

This model uses DN40 PN6/10 DIN flanges with a port-to-port length of 250 mm. Where dimensions match, it can replace other DN40 in-line circulators, subject to hydraulic duty and system requirements.

Can the motor be removed without draining the system?

Yes – the pump uses a top-pull-out design, so the power head can be removed while the pump housing remains installed in the pipework.
