Petromax · Pump · Operating Knob
Pump Knob blue HK150/HK250/HK350/HK500 The blue, knurled pump knob sits at the end of the pump rod and is the hand-held operating surface when building pressure. It is a grip part – not a sealing or pressure component.
Purchase decision: fits HK150, HK250, HK350 and HK500. Only the blue knob with Petromax lettering is delivered.

Fits well – and when rather not

Fits well if … … the pump knob is missing, cracked or damaged.
… the pump rod and its connection are intact.
… you want to visually and functionally complete an HK150 to HK500.


Fits rather not if … … the pump does not build pressure.
… pump leather, valve or rod are damaged.
… you are looking for the blue handwheel on the carburetor.


Features with practical effect

Knurled operating surface The edge improves grip when pulling and pushing the pump rod.


Blue with Petromax lettering The design is also suitable for visually completing a classic HK lamp.


Four HK models The Shopify data set lists HK150, HK250, HK350 and HK500.


Operating part only The knob transfers hand force to the rod. Pressure is generated by pump leather, pump chamber and valve working together.


Limits, disadvantages and avoiding bad purchases A new pump knob does not improve poor pressure build-up. For a smooth-running pump without delivery, first check pump leather and pump system. A damaged rod end is also not repaired by the knob.
Technical data with practical interpretation

Compatibility HK150 / HK250 / HK350 / HK500.


Design Blue, knurled, with Petromax lettering.


Function Hand grip of the pump rod – not a sealing part.


Part number 40-b – discreet for spare part allocation.


Scope of delivery 1 × blue Petromax pump knob
. Pump rod, pump leather, pump cover, valve, and complete pump are not included.
Safe use Work only on a cold, depressurized lamp. Before assembly, check the connection on the pump rod and attach the knob straight without force.
FAQ Is this the complete pump? No, only the handle knob is delivered. Does the knob fit the HK150? Yes, also fits HK250, HK350, and HK500 according to Shopify. Is the pump knob the same as the blue handwheel? No. The pump knob is on the pump rod; the handwheel operates the carburetor mechanism. Does it help with missing tank pressure? No. For that, pump leather, valve, and other seals need to be checked.
Black Raptor · honestly rated
A sensible single replacement for a damaged or missing handle knob. For real pump problems, the cause is almost always deeper in the pump system. (Show description in original language)

Petromax · Pumpe · Bedienknopf
Pumpenknopf blau HK150/HK250/HK350/HK500 Der blaue, gerändelte Pumpenknopf sitzt am Ende der Pumpenstange und ist die von Hand gefasste Bedienfläche beim Druckaufbau. Er ist ein Griffteil – kein Dicht- oder Druckbauteil.
Kaufentscheidend: passend für HK150, HK250, HK350 und HK500. Geliefert wird nur der blaue Knopf mit Petromax-Schriftzug.

Passt gut – und wann eher nicht

Passt gut, wenn … … der Pumpenknopf fehlt, gerissen oder beschädigt ist.
… die Pumpenstange und ihre Verbindung intakt sind.
… du eine HK150 bis HK500 optisch und funktional vervollständigst.


Passt eher nicht, wenn … … die Pumpe keinen Druck aufbaut.
… Pumpenleder, Ventil oder Stange beschädigt sind.
… du das blaue Handrad am Vergaser suchst.


Merkmale mit Praxiswirkung

Gerändelte Bedienfläche Der Rand verbessert den Griff beim Ziehen und Drücken der Pumpenstange.


Blau mit Petromax-Schriftzug Die Ausführung eignet sich auch zur optischen Vervollständigung einer klassischen HK-Lampe.


Vier HK-Modelle Der Shopify-Datensatz führt HK150, HK250, HK350 und HK500.


Nur Bedienteil Der Knopf überträgt Handkraft auf die Stange. Druck erzeugen Pumpenleder, Pumpenschacht und Ventil im Zusammenspiel.


Grenzen, Nachteile und Fehlkauf vermeiden Ein neuer Pumpenknopf verbessert keinen schlechten Druckaufbau. Bei leichtgängiger Pumpe ohne Förderung zuerst Pumpenleder und Pumpensystem prüfen. Ein beschädigtes Stangenende wird durch den Knopf ebenfalls nicht repariert.
Technische Daten mit Praxisdeutung

Kompatibilität HK150 / HK250 / HK350 / HK500.


Ausführung Blau, gerändelt, mit Petromax-Schriftzug.


Funktion Handgriff der Pumpenstange – kein Dichtteil.


Teilenummer 40-b – dezent für die Ersatzteilzuordnung.


Lieferumfang 1 × blauer Petromax Pumpenknopf. Pumpenstange, Pumpenleder, Pumpendeckel, Ventil und komplette Pumpe sind nicht enthalten.
Sichere Anwendung Arbeiten nur an kalter, druckloser Lampe durchführen. Vor Montage die Verbindung an der Pumpenstange prüfen und den Knopf ohne Gewalt gerade ansetzen.
FAQ Ist das die komplette Pumpe? Nein, geliefert wird nur der Griffknopf. Passt der Knopf zur HK150? Ja, ebenso zu HK250, HK350 und HK500 laut Shopify. Ist der Pumpenknopf dasselbe wie das blaue Handrad? Nein. Der Pumpenknopf sitzt an der Pumpenstange; das Handrad bedient die Vergasermechanik. Hilft er bei fehlendem Tankdruck? Nein. Dafür sind Pumpenleder, Ventil und weitere Dichtstellen zu prüfen.
Black Raptor · ehrlich eingeordnet
Ein sinnvoller Einzeltausch bei einem beschädigten oder fehlenden Griffknopf. Für echte Pumpenprobleme liegt die Ursache fast immer tiefer im Pumpensystem.
