ELECTRO HYDRAULIC PUMPS

A VETUS electro-hydraulic pump (EHP) consists of a reversible electric motor suppliers, an oil pump, built-in pressure relief valves and a small reservoir for the hydraulic oil. Models EHPA, EHPB and EHPC are provided with an axial plunger pump, with integrated non-return valves and a by-pass valve. Models EHPD and EHPE feature a gear type pump with integrated non-return valves and a by-pass valve. The direction of rotation of the pump is electrically controlled.

These models are only suitable for light duty pleasure craft.

EHPAR2 EHPBR2 EHPCR2

L 138 _

A VETUS EHP is a truly versatile piece of equipment. It can be used with "non Follow-Up" steering systems, with joystick control and/or electric remote control (see page 50), with "Follow-Up" steering systems, hatch lifters, collapsible swimming marine platforms etc. etc.

There is a choice of 5 EHP models:

Pressure relief valve settings:

40 bar for models EHPAR2 - EHPCR2 70 bar for models EHPD and EHPE Reservoir capacity:

0.2 litres for models EHPAR2 - EHPCR2 0.95 litres for models EHPD and EHPE Relays:

Integral and pre-wired for models EHPAR2 - EHPCR2. A double pole relay AFST1512D (12 Volt) or AFST324D (24 Volt) should be ordered separately for models EHPD and EHPE.


EHPAR2	with a capacity of 350 cm³/min.	17,1 sec/100 cm³
EHPBR2	with a capacity of 700 cm³/min.	8,5 sec/100 cm³
EHPCR2	with a capacity of 950 cm³/min.	6,3 sec/100 cm³
EHPD	with a capacity of 1425 cm³/min.	4,3 sec/100 cm³
EHPE	with a capacity of 1900 cm³/min.	3,1 sec/100 cm³

Current consumption:


EHPAR2	12 Volt	6,5	- 12 A	EHPAR2	24 Volt	5 -	6,5 A
EHPBR2	12 Volt	7,5	- 13,5 A	EHPBR2	24 Volt	5,5 -	7 A
EHPCR2	12 Volt	10	- 15 A	EHPCR2	24 Volt	5,7 -	10 A
EHPD	12 Volt		16 A	EHPD	24 Volt		9 A
EHPE	12 Volt		22 A	EHPE	24 Volt		11 A

Models EHPAR, EHPBR and EHPCR are supplied without hose fittings. Sets for 0 8 mm tubing (MTC30) and 0 10 mm tubing (MTC52 - MTC175 and OBC125 -OBC275) are available separately. Models EHPD and EHPE have 0 10 mm pipe fittings as standard supply.

SELECTION OF THE HARD OVER TO HARD OVER TIME FOR THE CYLINDER, IN COMBINATION WITH AN EHP

When used in combination with an automatic pilot, consult the instruction manual to select the desired hard over to hard over time. In most cases this will be between 7 and 23 seconds.

In the case of a remote steering system, either with a joystick or as a "Follow-Up" assembly, we recommend a cylinder hard over to hard over time of between 7 and 11 seconds.

Example: Cylinder MTC 72 has a capacity of 146 cm³ and a required hard over to hard over time of 20 seconds:

- Using model EHPAR the hard over to hard over time is 1.46 x 17.1 sec. = 25 seconds,

- Using model EHPBR the hard over to hard over time is 1.46 x 8 sec. = 12.4 seconds.

Therefore, model EHPBR should be selected.
