Grundfos TPD 100-70/4 cast iron twin-head in-line circulator pump, 1.5 kW 4-pole

Twin-head, close-coupled in-line pump: two identical 1.5 kW 4-pole fixed-speed motors and impellers on a common cast iron housing, with a flap valve in the discharge port so either head can run while the other stands by.

Built for closed heating, cooling and air conditioning circuits, with a top-pull-out design for easy service.

Key features

Cast iron pump housing

Robust cast iron housing for closed heating, cooling and air conditioning circuits.

Cast iron impeller

Cast iron (EN-GJL-200) impeller matched to the duty.

Top-pull-out design

Motor, pump head and impeller lift out as one unit while the housing stays in the pipework — no need to break the pipe joints for service.

Duty and standby

Two complete heads on one housing; a flap valve in the discharge port stops back-flow through the idle head. Changeover is by your control panel or BMS.

Mechanical shaft seal

BQQE seal to EN 12756 with silicon carbide faces — a standard seal, easy to source and replace.

IE4 4-pole motor

1.5 kW fan-cooled motor running at 1440 rpm, IP55 enclosure.

Frequently asked questions

What supply does it need?

Three-phase: 3 x 220-240 V delta / 380-415 V star. Connect the motor in delta on a 220-240 V supply or in star on a 380-415 V supply. Rated current is 5.51-5.31/3.19-3.07 A.

What will it pump?

Its rated duty point is 967 l/min (58 m³/h) at 5.4 m head, and it reaches up to 7 m (0.69 bar) at zero flow. Pipe and fitting losses are not included.

Can I control the speed?

This is a fixed-speed pump. For variable speed, look at the Grundfos TPE range, which has the speed control built into the motor.

What temperature and pressure can it take?

Liquid temperature -25 °C to +120 °C and a maximum operating pressure of 16 bar.
