Is there a pump that can operate at a lower speed (below 2900 revolutions per minute) while still achieving an outlet pressure of over 40 bar?

As the title suggests, the high-pressure centrifugal pumps that are commonly used these days are of the multi-stage type, with two motors; their rotation speed can reach around 3000 revolutions per minute, and the outlet pressure can exceed 40 bar. I would like to know whether there are any pumps available on the market that have a lower rotation speed (below 2900 revolutions per minute) while still being able to achieve an outlet pressure of over 40 bar. The fluid to be transported is either clean water, plant circulation water, or industrial water from steel mills. The type of pump is not restricted; I would appreciate advice from everyone. :handshake
Thank you. For a head of 400m, a flow rate of 50 m3/h, with clean water as the medium, which pump is recommended – a centrifugal pump or a positive displacement pump? What is the cost-performance ratio?

A multi-stage centrifugal water pump with a rotational speed of 1480 r/min, capable of achieving a head of up to 600 m.
