1. Introduction

The 7095 Hydraulic calibration hand pump is designed for ease of use with a fully
adjustable stroke control providing quick priming, easy pumping and a fast pressure
generation up to 700 bar (10,000 psi), fine control of the desired set point pressure is
achieved with use of the vernier control.

The pump has changeable built in filters to the output and gauge ports. The shatterproof
reservoir and stainless steel construction ensure reliable leak free operation.

plastic/rubber handles, PTFE, nitrile o-rings.
Weight: 1.36kg.

Contents

• 7095 pump

• Minimess/1/4” BSP high pressure hose

• 1/4” BSP blanking plug

• Selection of spare bonded washers, filters, washers and o-rings.

• Carry Case

2. Operational Notes

 Do not exceed 700bar (10,000 psi), the 7095’s maximum pressure.
 Do not try to achieve 700bar by pump action alone.
 The filler cap incorporates a small breather valve, it is normal for a very small amount of

media fluid to trickle out, especially if the pump is held horizontally.

 The 7095 comes with a 3/8” BSP gauge port fitted with a blanking plug and a 1/4" BSP

output port fitted with a capped Minimess 1620 test point.

 Use only bonded washers (Dowty) to seal adaptors.
 Use only with distilled water or mineral based hydraulic oil.
 Two bonded washers are fitted to seal the output port.

All Time Electronics' instruments are subject to continuous development and improvement and in

consequence may incorporate minor detail changes from the information contained herein.

3. Operation

3

1. Remove the reservoir fill cap, and fill with an approved fluid to the required level
(130 millilitres maximum). Refit the cap.

2. Connect the Minimess hose to the Minimess adaptor on the output port and connect to
the instrument under test.

3. Connect the calibrator with a suitable adaptor to the 7095 via the top gauge port.

4. Set the vernier control to about half its travel and fully screw in the release control
valve, no need to over tighten.

5. To prime the system, twist the knurled knob marked “Release” .Squeeze the handles
together and release. Twist the knob once again. Repeat until the system is fully primed
and a low pressure is indicated on either the UUT or on the calibrator. This feature can
be engaged at any pressure.

6. Be sure not to exceed the 700bar (10,000psi) maximum operating pressure
indicated on the pump. There is no pressure relief valve.Squeeze pump handles
raising the pressure to about 50% of final required pressure. Screw in the vernier
control to increase pressure to final set point, or screw out the vernier to decrease
pressure to desired set point.

7. If the fluid level in the reservoir falls considerably during use, a partial vacuum may be
created which could affect pump performance. To avoid this simply allow air to enter
the reservoir by partly unscrewing the filler cap. If the system demands more fluid,
remove cap and add more, do not over fill, the total amount in the system should not
exceed the capacity of the reservoir.

8. For fast controlled decompression, unscrew the release control valve.
