Npack manual liquid filling machine also called semi automatic liquid filling machine, all the working function and system is same.

Features of manual liquid filling machine:

1.without tank, it has a pipe which can connect with users storage tank

2.specially design For filling liquid

3.Filling range is from 10-50 ml ,50-100ml, 100ml to1000ml,900ml to 5000ml

4.Capacity :10-30bottles/m for 100ml

5.One filing nozzle standard , 2 filling nozzles optional

6.Leaking-Proof, Silk Nuzzling-Proof, Leakage recovery system

7.Machine construction material are mainly 304SS, the hopper and liquid contact parts are 316L stainless steel

8.pneumatic driven system , no need electric but need air compressor

We classify the types of manual liquid filling machine by the maximum filling volumes which most customers require.

NP-Ss are divided into 6 basic types as follows:

NP-S-3  (15~30ml)

NP-S-6  (15~60ml)

NP-S-12 (30~120ml)

NP-S-25 (60~250ml)

NP-S-50 (120~500ml)

NP-S-100 (250~1000ml)

NP-S-500（500-5000ml）

Working principle

The working principle of ourmanualc liquid filling machine is explained as follows: the cylinder’s moving back and forth makes the piston reciprocate, thus, negative pressure is created in the front of the material tank.

The cylinder draws the piston back when it moves back, which makes negative pressure in the front of the material tank. Then material inside the reservoir is atmospherically pumped into the material tank via an intake soft pipe and a three-way pipe.

The cylinder draws the piston forth when it reverses. Meanwhile, the one-way valve opens, permitting squeezed material escaping from the material tank through outlet soft pipe to a nozzle, and then the nozzle dispenses material into bottles. The filling nozzle is closed when sucking out material, and verse vice. In this way, once filling is finished.

Our NP-S has high precision and stability to every regular container, because each filling is a unitary and mechanical motion.

Adjustment of filling volume

The filling volume depends on the capacity (ml) or weight (g) that the user wants. Because the specific gravity of material ranges greatly, the same data on the survey meter may be not applicable for all materials. The distance control switch can be accommodated to obtain an exact data.

Detailed operations are as follows:

1) Rough adjustment: Move the adjustment screw left and right in order to regulate of advancement air control switch. Adjust the screw of backhaul air control switch properly to reach the satisfied position.

2) Place a measuring cup or a stuff bottle below the nozzle. (Notes: a full material tank ensures high accuracy and vice versa.) Put the cup or bottle onto an electronic balance to check out whether the filling volume is accurate.

3) If error still exists, it is essential to regulate the backhaul distance control switch through the handwheel. Filling volume increases when the adjuster slides left, and vice versa.

4) Adjust repeatedly until it reaches the proper filling volume and precision.
