Overview
Most 315 enquiries arrive with a number rather than a specification: 151Z3011, 151Z3017 or 151Z3021 already fix the frame size, the shaft style and the port standard. Because the mounting platform is shared across the TMT range, a machine can be returned to service without modifying the flange, the hoses or the shaft coupling.
The 315 frame sits between the faster 250 and the torquier 400 and is often chosen when one displacement has to serve two duties. Constant torque is available over a wide speed range, starting torque is high for a low-speed orbital design, and the motor accepts high return pressure, which keeps plumbing simple on compact machines.

Ordering & support
1. Send the existing code number, nameplate photo or machine serial.
2. We confirm frame size, shaft, flange and port standard against the drawing.
3. Shaft, flange and variant (TMTU, TMTW, TMT FL) are quoted to match the installation.
4. Export packing, shipping documents and technical data sheet prepared with the order.
FAQ
Which part numbers identify a TMT 315?
The standard European build is 151Z3011, the Ø125 mm flange build is 151Z3017 and the splined shaft version is 151Z3021. Other combinations use further codes in the same 151Z30xx block.
Can the motor run in a closed loop circuit?
Yes. TMT motors suit open and closed loop systems; where oil renewal and cooling are needed in a closed circuit, specify the integrated flushing valve version.
What is the maximum continuous pressure?
250 bar pressure drop continuously, 350 bar intermittently and 400 bar at peak. Intermittent operation is limited to 10% of every minute and peak to 1%, and the two ratings cannot be added together.
