For a good part of the steam era until the 1920's when most of the
British companies were amalmagated into larger ones a fair number used
the Westinghouse air brake and it existed in small pockets for much
later.
Here is a Loco that has been kept from that era with it's pump visible
in the 3rd photo down.

The Isolated Isle of Wight network which was worked for years with
ancient stuff retired from the mainland was entirely Westinghouse till
most of it closed in 1966.

Realistically British locos only needed the pumps for passenger stock,
freight stock being unbraked and relying on the crew member in the
brake van/caboose to use a manual brake in the van where needed and
partial applications of manual wagon brakes before a train set off
down a gradient. And British trains compared to most were short.
So they didn't need the pump capacity of a North American Loco
like the one you featured below.
