HMS 20/2

Our most convenient mobile make-up/topping unit for refilling operations with (non-) pressurised seal flushing systems. The mobility of these refill units will let you charge multiple seal flushing systems with a single make-up unit, reducing cost and service needs. 

Should you prefer fixed units for integration within each sealing system separately, kindly refer to our range of HMF refill units.

HMS / Ordering code

HMS  –  V /2  –  MC – P
(HMS is code for the basic equipment)

Material configuration options:


V = seal liquid reservoir volume in L.:

10 20 50(*1) (V is standard followed by /2)


MC = Material Configuration

W Anodised alloy for mineral oils and water
SW Stainless steel / bronze for mineral oils,
water and most other liquids


P = maximum charge pressure in barg(*2):

16, 25, 40, 60, 100, 160, 200

(*1): 50 L. shall be selected only for use on rather clean, flat and hard-surfaced pavements or else a 4-wheel trolley is recommended. Refer to our range of HMS 50/4 refill and topping-up units.   

(*2): select a pressure range that is ≥20% above the desired charging pressure. For example: you need to charge to 28 barg which defines a requirement of plus 20%, is 33.6 barg, Select 40. 

For example

The ordering code HMS-20/2-SW-40 specifies a highly convenient mobile HMS make-up/refill unit, that is provided with a 20 L. reservoir on a convenient 2-wheel trolley, and is constructed of mainly stainless steel 316 materials. The nominal pressure capacity is 40 barg, best selected for a maximum operational pressure of 32 barg.



Unit can be automated using an air driven pump for ease of operation


A steerable 4-wheel trolley for higher reservoir volumes and larger service range. Please refer to our range of HMS 50/4 units.


Soft parts in EPDM or Viton available on request.
