GENERAL INFORMATION

Thanks to GHIM HYDRAULICS’ long lasting experience in this branch, a brand new family of hand pumps with iron casthousing has added to its range of products in order to fulfill the most demanding requirements of the market

CAST IRON “GH” HAND PUMP RANGE

All of the “GH” series hand pumps can be supplied with or without the following accessories: manual lever, plasticprotection bellow and tank. Each model is available with relief valve upon request.

SERIES “GH-HPR”The “GH-HPI” series is made of monocylindrical, double acting hand pumps withexhaust valve. Three different models are available: 45 – 25 – 12 cm3 /cycle.

SERIES “GH-HPI”Series “GH-HPI”, it is made of monocylindrical, double acting hand pumpsequipped with a double acting valve capable of directing flow toward twoindipendent branches of the hydraulic circuit. Three different models areavailable: 45 – 25 – 12 cm3 /cycle.

SERIES “GH-HPM”Series “GH-HPM” is made of monocylindrical, double acting hand pumpswith or without exhaust valve. They are available in two different models: 20 –50 cm3/cycle.

Models equipped with relief valve will be supplied with the valve adjusted at the nominal pressure settings, whose valuesare shown in Table 1 (Standard pressure settings of the relief valve).

In case the hand pump is requested complete with tank, the following capacities are available: 1 –2 – 3 – 5 – 7 – 10liters.

In order to make pump installation to tank easier, a suitable weldable flange made of steel is available.

These pumps can be delivered “custom made” and are available in kit form along with an hydraulic cylnder ,hoses and fittings. The “GH” range made of cast iron is divided into 3 groups according to the relevant duty.

APPLICATIONS

The hand pumps in object can be used for several applications, such as INDUSTRY, AGRICOLTURE,TRANSPORTATIONS, MILITARY and NAVAL.

RELIABILITY

The accurate design followed by severe testing procedures applied on the homologation benches and labs allowed us toachieve a very high degree of reliability and lifetime of our products. The body of pump is normally supply with surfacephosphate treatment. Under request the body of pump is available painted or zinc plated.

PUMP HYDRAULIC SCHEME

In picture 1 (hydraulic scheme of the “GH-FPR” – “GH-HPE” – “GH – HPI” – “GH-HPB” – “GH-HPM” pumps)conventional hydraulic schemes of the same “GH” series are shown.

HPM” pumps)

INSTALLATION AND SERVICE

GENERAL USE CONDITIONS

Temperature range for a correct use of the “HP” pumps is included between –15°C and +80°C.

In order to make sure that the pump is performing correctly, use exclusively good quality hydraulic oil with 2÷6 °Eviscosity at 50°C. Periodically checking oil cleanliness and possibly carrie on proper filtration by means of a 35 µm.filter is strongly recommended.

Special versions are available upon request in case of particular environment conditions (for example in low temperaturesuch as –45°C etc.).

Do not hesitate to contact our sales department in order to properly chose pump models required for thespecifical applications.

PUMP INSTALLATION

“HP” PUMP FITTING POSITIONS

Installation position of the pump must be chosen according to tank size.

Pump with tank

In sections A and B of Pic.2 (Pump to tank installation) the standard fitting positions of the hand pumps complete withtanks are shown.

In case position “C” is going to be chosen, check following steps before starting the installation:

1) Remove pump from tank flange unscrewing the four M8 screws;

2) Rotate suction pipe of 180°;

3) Fit pump into original position taking care of the correct position of the gasket;

4) Tighten M8 screws with sufficient torque.

Position “A” Position “B” Position “C”

Pic.2 (Pump to tank installation)

Pump installation to tank with flange

In case the pump is going to be fitted to a steel tank by means of a flange, a suitable weldable plate is available asshown in Pic. 3 (weldable flange)

SERVICE

GENERAL SERVICE

Basic service consists of the following operations:

- Suction filter cleaning.

- Remove rubber cover from suction section.

- The filter is located inside the cover.

- Non return valve cleaning in the suction section.


- Remove threaded plug from cylinder.

- Non return valve is located inside the plug.

- Non return valve cleaning inside piston.


- Remove threaded plug from cylinder.

- Remove rod from the bottom of the pump

- Non return valve is located in the lower rod section.

Relief valve adjustment

With reference to Pic. 4 (Relief valve) relief valve adjustment is done as follows:

1. Remove plug

2. Tighten grub screw to increase pressure and viceversa to reduce it.

3. Place plug back to its original position and tighten with adequate torque.

LEVER OPERATION

In order to operate the lever properly, please refer to Pic. 6 (Power to be applied to pump lever) about suitable powerapplication to it (load scheme for the lever).

LegendaA = move up

R = move down

L = lenght = 600 mm

F = power to be applied to lever end.
