HMF 2.5 / 5 /10 Ltr.

Stand-alone make-up/topping units for refilling operations with (non-) pressurised seal flushing systems. These units are best suited for integration within a seal flushing system. Retrofitting options available as well.


Standard configuration

A high quality stainless steel Micropac® robust and compact hand pump with:


  • A high stroke capacity – up to 75cc p/str) to minimize refill time
  • Hard chrome plated stainless steel piston rod for durable operation
  • A stainless steel liquid reservoir of 2.5, 5 or 10 Ltr. (5 is recommended)
  • Any pressure capability up to 200 bar (std.= 40 bar)
  • Complete with overload protection valve
  • Complete with a 9/16” UNF* high-pressure charging connection

 (*) Alternative connections available on request. When ordered together with a Flopac® seal support system, Flopac will arrange for the proper connections and integration within the system.

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

(*): 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 HMF-5-SW-40 specifies a HMF make-up/refill unit, that is provided with a 5 L. reservoir 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


Unit can be provided with a pressure release valve


Instead of one refill unit per each seal flushing system one could consider a mobile unit to serve multiple systems. Please refer to our range of HMS refill units


Soft parts in EPDM or Viton available on request


Level gauge i.s.o. dipstick


Other charging connections (f.i. 1/4” or 1/2” BSP/NPT, flanges etc.) available on request


ATEX certification if and as needed
