No.2 DAWSON & DOWNIE of Clydebank. A two-cylinder horizontal duplex non-rotative steam-driven high-pressure hydraulic pump, with "crossed" valve drive similar in style to those made by Worthington-Simpson and Hayward-Tyler.
Nameplate: Pump No 25573. Size 10½” x 2⅜” x 10”, assumed to be steam bore x pump bore x and common stroke. Pump pressure therefore approx. twenty times steam pressure.
The steam slide valve cover is angled (to give access to the seats and, presumably, to allow valves to be withdrawn endways off the rod). This cover has been put on backwards at some time past (before coming here).
Each double-acting pump has a hefty cross-head at each end joined by tie bars running in plain guides. Each pump has paired suction and delivery non-return valves; suctions are on opposite sides, but delivery connections are on top, joined via a common output pipe having a pressure-relief valve on top. Most metalwork is protected by shabby paint, but there is some rusting of piston rods and in patches on the guide bar.
